| CVE-2026-97491 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net/rds: Don't sleep inside rds_ib_conn_path_shutdown New rds rdma self tests exposed a hang when tearing down the ib network configs. This is caused by the shutdown worker thread sleeping on the wait_event call, which blocks other work items in the queue. Fix this by changing wait_event to wait_event timeout, and looping until the wait check succeeds. | ||||

| In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: don't call ieee80211_handle_reconfig_failure when not needed In case reconfiguration of NAN fails, we call ieee80211_handle_reconfig_failure, that marks all interfaces as not in the driver. Then, at the error path of the reconfig, cfg80211_shutdown_all_interfaces is called to destroy all the interfaces. If we have any other interface but the NAN one, for example a BSS station, then when its state (links, stations) will be removed, we won't tell the driver about this, because we will think that the interfaces are not in the driver, and then drivers might remain with dangling pointers to objects like stations and links (at least for iwlwifi this is the case). ieee80211_handle_reconfig_failure is meant to be called after we cleaned up the state in the driver, there is no reason to call it for NAN reconfiguration failure. Fix the code to just warn in such a case, as we do in other error paths in reconfig where it is too complicated to rewind. | ||||
| CVE-2026-97493 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Bound GPIO I2C table entry count from VBIOS Reject undersized tables and cap the derived entry count to AMDGPU_MAX_I2C_BUS so we do not overrun adev->i2c_bus[] or walk an absurd number of entries on corrupt size fields. | ||||
| CVE-2026-97511 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: avoid out-of-bounds access in monitor In NAN, we don't know on what band the frame will be sent. Therefore we set info->band to NUM_NL80211_BANDS. However, this leads to out-of-bound access in ieee80211_add_tx_radiotap_header when we try to access the sbands array. Fix it by not accessing the array if the band is NUM_NL80211_BANDS. This means that we will not report rate info for legacy rate in NAN. But nobody really cares about it. | ||||
| CVE-2026-97533 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: x86/mm/pat: Acquire init_mm read lock on attribute changes to avoid UAF A previous commit protected against races between ptdump and CPA collapse, however one still exists between attribute changes and collapse as reported by Denis V. Lunev (linked). When an attribute change arises, a lockless page table walker obtains a PTE entry, which is later written to via set_pte_atomic(): ... -> change_page_attr_set_clr() -> __change_page_attr_set_clr() -> __change_page_attr() -> _lookup_address_cpa() -> lookup_address_in_pgd_attr() -> [ lockless page table walker ] -> set_pte_atomic() There is nothing preventing a concurrent CPA collapse which can free the PTE that was retrieved here, resulting in a use-after-free. With the mmap write lock taken on init_mm over CPA collapse, resolve this race by acquiring an mmap read lock on init_mm over __change_page_attr_set_clr(). This locks across the whole operation over which the walk and the PTE entry write occurs, solving the race. It is safe to do this here, as no spinlocks are held upon entry to __change_page_attr_set_clr(). However, the lock must not be held over an allocation, as allocation can trigger reclaim and shrinkers may call into CPA recursively, making deadlocks possible (init_mm -> ... -> fs_reclaim -> init_mm). A page table is allocated when a huge page needs to be split: -> change_page_attr_set_clr() -> __change_page_attr_set_clr() -> __change_page_attr() -> split_large_page() [ pagetable_alloc() ] -> __split_large_page() Avoid deadlocks by dropping the mmap lock across pagetable_alloc() in split_large_page() and track whether this is needed by adding a new 'init_mm_read_locked' flag to struct cpa_data. This is safe as __split_large_page() (called with locks re-established) revalidates that the page table entry is the same as it was prior to the locks being dropped and __change_page_attr() repeats the entire page table walk whenever a split occurs, so concurrent split and collapse are accounted for. Concurrent ptdump is also safe as the lock is only dropped over page table allocation during which time the page table has not yet been modified. The CPA_COLLAPSE flag is only set by set_memory_rox(), which exclusively operates upon vmalloc ranges, and on x86 only within the module mapping space. This is important, because some callers directly invoke __change_page_attr_set_clr(), bypassing this lock. However, none of these operate within the module mapping space. * cpa_process_alias() - a recursive helper called by __change_page_attr_set_clr(). * __set_memory_enc_pgtable() - operates on the direct mapping and (via __vmbus_establish_gpadl()) the vmalloc mapping space. * __set_pages_[n]p() - called by set_direct_map_[invalid, default, valid]_noflush(), __kernel_map_pages() - operates on the direct map. * kernel_[un]map_pages_in_pgd() - operates on EFI ranges. This work is based upon Denis V. Lunev's excellent analysis of the bug with gratitude. [ dhansen: move to imperative voice in changelog ] | ||||
| CVE-2026-97495 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Check bounds on allocate_doorbell allocated_doorbell has an option to set the doorbell id to a specific value (used by CRIU). This value was not bounds checked. Check to confirm it's less than KFD_MAX_NUM_OF_QUEUES_PER_PROCESS. | ||||
| CVE-2026-97496 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix OOB memory exposure in get_wave_state() The get_wave_state() function for v9 trusts cp_hqd_cntl_stack_size and cp_hqd_cntl_stack_offset values read directly from the MQD, which are written by GPU microcode and fully attacker-controlled on the CRIU-restore path (via AMDKFD_IOC_RESTORE_PROCESS with H3). this leads to an unbounded copy_to_user() that can leak adjacent GTT/kernel memory. If offset > size, integer underflow produces a ~4 GiB read length, if size is set to 1 MiB against a 4 KiB allocation, we leak 1 MiB of adjacent kernel memory (other queues' MQDs, ring buffers, KASLR pointers). Fix by clamping both cp_hqd_cntl_stack_size to the actual allocated buffer size (q->ctl_stack_size) and cp_hqd_cntl_stack_offset to the clamped size before performing arithmetic and copy_to_user(). This ensures we never read beyond the allocated kernel BO regardless of attacker-supplied MQD field values. | ||||
| CVE-2026-97525 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 8.2 High |
| In the Linux kernel, the following vulnerability has been resolved: x86/mm/pat: Allocate split page tables as kernel page tables A PTE is allocated directly without going through the standard page table allocation routines (such as pte_alloc_one_kernel()) when the CPA code splits a large page (__split_large_page()). This means the page table constructor is never called nor is the page table marked as a kernel page table. The former results in the folio associated with the page table not being marked as a page table (__pagetable_ctor() is never called thus neither is __folio_set_pgtable()) nor are statistics updated to reflect it (lruvec_stat_add_folio() is never called). The latter issue of failing to mark the page table as a kernel page table (ptdesc_set_kernel() is never called) is far more problematic. Since commit: 5ba2f0a15564 ("mm: introduce deferred freeing for kernel page tables") kernel page table freeing has been batched and since the subsequent commit: e37d5a2d60a3 ("iommu/sva: invalidate stale IOTLB entries for kernel address space") IOTLB cache entries for kernel page tables have been invalidated upon being freed. Since split page tables are freed without this invalidation, the IOTLB can contain stale entries for them. Resolve the issue by using the ordinary PTE allocation API at split time. This results in these kernel page tables invoking a page table constructor, and thus requires a page table destructor. Destructors are not always present, like for early allocated direct map page tables). Conditionally call pagetable_dtor_free() if the PG_table folio flag for the ptdesc is set, otherwise we free the page table via pagetable_free(). Regardless of which path is taken page tables marked as kernel page tables, which now includes split page tables, take the correct route through pagetable_free_kernel(). There is a user-visible side effect in that split page tables will appear in nr_page_table_pages in /proc/vmstat (as do other kernel page tables allocated after early boot), however this is a positive change. This issue started being markedly problematic after commit: 5ba2f0a15564 ("mm: introduce deferred freeing for kernel page tables") so choose this as the Fixes target.

| CVE-2026-97501 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: pinctrl: mediatek: paris: bypass pinctrl GPIO layer in set GPIO direction pinctrl_gpio_direction_input() / pinctrl_gpio_direction_output() take the pinctrl mutex. This causes a gpiochip operations to need to sleep. Worse yet, the .can_sleep field in the gpiochip is not set. This causes the shared GPIO proxy to trip over, as it uses gpiod_cansleep() to check whether it can use a spinlock or needs a mutex. In this case, it ends up taking a spinlock, then calls pinctrl_gpio_direction_output(), which takes a mutex. This causes a huge warning. While this class of Mediatek hardware does not have separate clear/set registers, the pinctrl context has a spinlock that is taken whenever a register read-modify-write is done. Also, once the GPIO function is selected / muxed in, further GPIO operations do not involve pinctrl operations or state. The GPIO direction and level values do not require toggling the pinmux or any other pin config options. Switch to directly calling mtk_pinmux_gpio_set_direction() in the GPIO set direction callbacks to avoid taking the pinctrl mutex. Drop the .gpio_set_direction field in mtk_pmxops to signal we are no longer using the pinctrl GPIO layer for setting the direction. | ||||
| CVE-2026-97503 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: genirq/proc: Size interrupt directory names for 10-digit interrupt numbers /proc/irq/<n>/ directory names are built in `char name[10]` buffers with `sprintf(name, "%u", irq)`. Ten-digit IRQ numbers already need 11 bytes including the trailing NUL, and current sparse-IRQ configurations allow interrupt numbers in that range. Size the temporary name buffer for the current decimal form and switch to bounded formatting when creating or removing the proc entry. | ||||

| CVE-2026-97505 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: PCI/sysfs: Add CAP_SYS_ADMIN check to __resource_resize_store() Currently, the __resource_resize_store() allows writing to the resourceN_resize sysfs attribute to change a BAR's size without checking for capabilities, currently relying only on the file access check. Resizing a BAR modifies PCI device configuration and can disrupt active drivers. After the upcoming conversion to static attributes, it will also trigger resource file updates via sysfs_update_groups(). Add a CAP_SYS_ADMIN check to prevent unprivileged users from performing BAR resize operations. | ||||
| CVE-2026-97530 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix soft lockup polling continuation IOCB signature qla27xx_copy_multiple_pkt() and qla27xx_copy_fpin_pkt() poll rsp_q->ring_ptr->signature for RESPONSE_PROCESSED (0xDEADDEAD) to decide whether the next continuation IOCB has arrived, spinning on cpu_relax() without advancing the ring or decrementing the entry count while it has not. response_t::signature lives at byte offset 60, but a continuation IOCB (sts_cont_entry_t / struct sts_cont_entry_ext) carries raw FC frame payload at that offset (data[56..59]). A received frame whose payload bytes happen to equal 0xDEADDEAD is therefore misread as "not yet arrived", and the loop spins forever in interrupt/DPC context, causing a CPU soft lockup. The poll is also unnecessary: callers of qla27xx_copy_multiple_pkt() (PT_LS4_UNSOL and the NVMe purls path) already gate on qla_chk_cont_iocb_avail(), which guarantees all entry_count IOCBs are present before copying begins. The sibling helper __qla_copy_purex_to_buffer() already drops the signature poll and relies on the entry_type == STATUS_CONT_TYPE guard instead. Remove the signature busy-wait from both helpers, keeping the entry_type guard, and gate the FPIN path with qla_chk_cont_iocb_avail() so it defers and re-processes on the next interrupt once all continuation IOCBs have arrived, mirroring the ELS_AUTH_ELS and PT_LS4_UNSOL arms. With this the signature field is never read on a continuation IOCB, eliminating the payload-aliasing lockup. | ||||
| CVE-2026-97536 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix use-after-free of qpair work on queue teardown The response queue MSI-X handler qla2xxx_msix_rsp_q() schedules qla_do_work() via queue_work(ha->wq, &qpair->q_work). qla_do_work() dereferences the qpair (vha, rsp) and takes qpair->qp_lock. During teardown, qla2xxx_delete_qpair() deletes the response queue, which calls free_irq() in qla25xx_free_rsp_que(), and then frees the queue and the qpair. free_irq() waits for running hardirq handlers but does not cancel work already placed on ha->wq. A still-pending q_work then runs qla_do_work() against the freed qpair and response queue, causing a use-after-free. This is especially likely during full adapter teardown, where destroy_workqueue(ha->wq) forces pending work to run after the queue pairs have been freed. Flush the work item with cancel_work_sync() in qla25xx_free_rsp_que() after free_irq() has released the interrupt (so no new work can be queued) and before the response queue and qpair memory are freed (so the flushed handler still sees valid memory). Guard on rsp->qpair and ha->wq to match the INIT_WORK() condition and avoid operating on an uninitialized work_struct. | ||||
| CVE-2026-97513 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: media: chips-media: wave5: Release m2m_ctx after Instance Removed from List Possible use after free if IRQ thread manages to obtain spinlock between m2m_ctx release and wave5_release function removing stream instance from list of active instances. The IRQ thread looks for the m2m_ctx which is freed so null pointer dereference occurs. | ||||
| CVE-2026-97522 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: mptcp: fix bad accounting in __mptcp_subflow_push_pending() If __subflow_push_pending() errors out we should avoid updating the copied byte counters, to avoid mismatch push call later on. | ||||
| CVE-2026-97528 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Unlink NVMe unsol ctx before freeing on LS reject error qla_nvme_xmt_ls_rsp() obtains uctx, which was linked into fcport->unsol_ctx_head by qla2xxx_process_purls_iocb() and is still linked when the NVMe transport calls back to transmit the LS response. On the error (out:) path the function frees uctx with kfree() but never removes it from the list. This leaves a freed node in fcport->unsol_ctx_head: the next list_add_tail() for that fcport writes through the freed node, and a subsequent list_del() can corrupt the list or panic. Unlink uctx with list_del() before kfree() on the error path, matching the other free sites in qla_nvme_release_lsrsp_cmd_kref() and qla2xxx_process_purls_pkt(). qla2x00_rel_sp() in the failure path only returns the SRB to its pool and does not invoke sp->put_fn, so the out: path is the sole free and uctx is always still linked there. | ||||

| CVE-2026-97532 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Null out freed pointers in qla2x00_mem_alloc() error path When qla2x00_mem_alloc() fails, qla2x00_probe_one() jumps to probe_hw_failed and calls qla2x00_mem_free(). Several error labels in qla2x00_mem_alloc() freed adapter members (elsrej.c, purex_dma_pool, flt, sfp_data, loop_id_map, async_pd, sf_init_cb, ex_init_cb, npiv_info) but left the pointers dangling. qla2x00_mem_free() then freed them a second time. Worse, for the dma_pool members it issued dma_pool_free(ha->s_dma_pool, ...) after s_dma_pool had already been destroyed and set to NULL at fail_s_dma_pool, dereferencing a NULL pool. Clear each freed pointer (and its DMA handle) in the error labels so the subsequent qla2x00_mem_free() skips them. | ||||
| CVE-2026-97535 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Bound VP index against VP_CTRL IOCB bitmap size The VP control IOCB selects its target virtual port by setting one bit in vp_idx_map, a fixed 16-byte (128-bit) array in both vp_ctrl_entry_24xx and vp_ctrl_entry_24xx_ext. qla25xx_ctrlvp_iocb() computes map = (vp_index - 1) / 8 and writes vce->vp_idx_map[map] without checking that map stays within the array. max_npiv_vports is taken from firmware and only sanitized to a MIN_MULTI_ID_FABRIC-aligned boundary, so it can legitimately be 191 or 255, and qla24xx_control_vp() only rejects vp_index >= max_npiv_vports. A vp_index above 128 therefore yields map >= 16 and an out-of-bounds write of up to 16 bytes past vp_idx_map, corrupting the trailing IOCB fields (or the adjacent request-ring slot on the 64-byte layout). Reject a vp_index that cannot be represented in the IOCB bitmap in qla24xx_control_vp(), and add a defensive ARRAY_SIZE() guard in qla25xx_ctrlvp_iocb() before the write. Adapters that report the usual 63 or 127 NPIV vports are unaffected. | ||||
