| Use of an Externally Controlled Format String in the ASUS Router modules allow a remote authenticated user to execute arbitrary commands via a crafted file uploaded through the web management interface. |
| NVIDIA GPU Display Driver for Linux contains a vulnerability where a user might be able to cause a format string issue. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, data tampering, denial of service, and information disclosure. |
| A format string vulnerability in the API endpoint of HPE Networking Instant ON APs could allow an authenticated remote attacker with high privileges to cause memory corruption with a modified input. Successful exploitation could allow an attacker to provoke a denial-of-service condition or remote code execution in the affected system function. |
| Uncontrolled Format string vulnerabilities exist in the affected interface of HPE Networking Instant ON APs that could allow an unauthenticated remote attacker to run arbitrary commands on the underlying host. Successful exploitation could result in a Denial-of-service or potential remote code execution. |
| NVIDIA GPU Display Driver for Linux contains a vulnerability in the kernel mode layer where an unprivileged user could cause a double-free of imported memory state. A successful exploit of this vulnerability might lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering. |
| In the Linux kernel, the following vulnerability has been resolved:
nvme-rdma: fix -EIO cleanup order in queue_rq
On -EIO, the RDMA queue_rq path reports a host path error and then
still cleans up the command and unmaps the SQE DMA. The path error
helper completes the request, so that is double cleanup and DMA unmap
after the request is already complete.
Unmap the SQE first, then report the host path error. Skip the outer
command cleanup on that path. |
| In the Linux kernel, the following vulnerability has been resolved:
afs: Fix double-unmap of directory block
Fix afs_edit_dir_remove() to use a cleanup function to unmap the block
pointed to by afs_dir_iter::block if it's left pointing to something rather
than manually kunmapping the blocks. Manually kunmapping without clearing
iter.blocks can result in a double-kunmap if afs_dir_find_block() is called
twice in a row (which would be the case if the block being modified is not
first in the hash chain). |
| Use of externally-controlled format string in Active Directory Certificate Services (AD CS) allows an authorized attacker to disclose information over a network. |
| 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. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: caiaq: Fix potential double-free at error path
The fix for caiaq driver's resource management to handle the errors
tries to release the resources in a common destructor call, but as a
sashiko review for another patch suggested, some of the audio
resources such as URBs have been already freed, and this may lead to a
double-free.
For addressing the double-free, call the common destructor function
from each place, and assure that the resource pointers get cleared. |
| In the Linux kernel, the following vulnerability has been resolved:
virtio-fs: avoid double-free on failed queue setup
virtio_fs_setup_vqs() allocates fs->vqs and fs->mq_map before calling
virtio_find_vqs(). If virtio_find_vqs() fails, the error path frees both
pointers and returns an error to virtio_fs_probe().
virtio_fs_probe() then drops the last kobject reference, and
virtio_fs_ktype_release() frees fs->vqs and fs->mq_map again. This leaves
dangling pointers in struct virtio_fs and can trigger a double-free during
probe failure cleanup.
Set fs->vqs and fs->mq_map to NULL immediately after kfree() in the
virtio_fs_setup_vqs() error path so that the later kobject release sees an
uninitialized state and kfree(NULL) becomes harmless.
This can be reproduced when a broken virtio-fs device advertises more
request queues than the transport actually provides. In that case
virtio_find_vqs() fails while setting up the extra queue, and the probe
path reaches the double-free cleanup sequence. |
| In the Linux kernel, the following vulnerability has been resolved:
ieee802154: hwsim: serialize pib updates to fix double-free
hwsim_update_pib() does an unserialized read-swap-free of phy->pib:
pib_old = rtnl_dereference(phy->pib);
...
rcu_assign_pointer(phy->pib, pib);
kfree_rcu(pib_old, rcu);
It assumes the RTNL is held, but ->set_channel is not always called
under it: the mac802154 scan worker changes channels via
drv_set_channel() without the RTNL. Such an update can race an
RTNL-held one on the same phy; both read the same pib_old and both
kfree_rcu() it, double-freeing the object. With SLUB percpu sheaves
batching kfree_rcu(), this surfaces as a KASAN invalid-free in
rcu_free_sheaf().
struct hwsim_phy has no lock for pib. Add one and make the swap atomic
with rcu_replace_pointer() under it, dropping the misleading
rtnl_dereference(). |
| In the Linux kernel, the following vulnerability has been resolved:
staging: fbtft: make dirty_lock IRQ-safe
fbtft_mkdirty() can be reached from the fbcon rendering path while
processing printk() in hardirq context. Meanwhile, dirty_lock is also
taken by fbtft_deferred_io() in workqueue context with local interrupts
enabled.
Lockdep reports a possible IRQ lock inversion involving dirty_lock and
console_owner. A hardirq can interrupt a CPU holding dirty_lock and
enter the console rendering path, which can attempt to acquire
dirty_lock again.
The following lockdep report was observed on an RK3566 system with
CONFIG_PROVE_LOCKING enabled:
WARNING: possible irq lock inversion dependency detected
swapper/2/0 just changed the state of lock:
(console_owner){-...}-{0:0}
but this lock took another, HARDIRQ-unsafe lock in the past:
(&par->dirty_lock){+.+.}-{2:2}
CPU0 CPU1
---- ----
lock(&par->dirty_lock);
local_irq_disable();
lock(console_owner);
lock(&par->dirty_lock);
<Interrupt>
lock(console_owner);
*** DEADLOCK ***
Use spin_lock_irqsave() for fbtft_mkdirty() and spin_lock_irq() for
fbtft_deferred_io(). They only access the dirty line range, so the
IRQ-off regions remain short. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/ras: add ras_suspend callback and use it for cp_ecc_error_irq
cp_ecc_error_irq is acquired in amdgpu_gfx_ras_late_init() but
released in gfx_v9_0_hw_fini(), so the put site has to query
amdgpu_irq_enabled() because the get is skipped on SR-IOV VF.
ras_late_init / ras_fini have no suspend counterpart, so move the
put to amdgpu_gfx_ras_suspend() / amdgpu_gfx_ras_fini() and add a
matching ras_suspend callback that is invoked from
amdgpu_ras_suspend() before disable_all_features(). The get and
put now sit in the same place and check the same condition (not
VF, funcs registered), no refcount querying needed.
An active flag gates ras_fini so the
suspend-then-unload-without-resume path falls into
amdgpu_ras_block_late_fini_default() instead of double-releasing
what ras_suspend already cleaned up.
Drop the cp_ecc_error_irq put from gfx_v9_0_hw_fini(). gfx_v8_0
manages cp_ecc_error_irq locally and is unaffected; no other GFX
generation has this IRQ. |
| A flaw was found in CRI-O. The fix for a previous vulnerability (CVE-2022-4318) was incorrect, allowing it to be bypassed. An attacker capable of setting environment variables on a container can inject a newline character into the HOME environment variable. This issue allows the addition of arbitrary lines into /etc/passwd by use of a specially crafted environment variable. |
| A flaw was found in Red Hat Ansible Automation Platform's automation-
controller. The setting that formats the log message emitted for API 4XX errors
is an administrator-controlled Python format-string template that is rendered
with a live user object as an argument. Because Python string formatting permits
attribute and item traversal on its arguments, an administrator can craft a
template that walks from the user object into the application settings and reads
the Django secret key and the database password. The formatted message is written
to a logger that can be forwarded to an external log aggregator, whose destination
is also administrator-controlled, allowing the secrets to be sent off the host. An
authenticated administrator can thereby obtain the master encryption key used to
protect all stored credentials and the database service password, enabling offline
decryption of every stored credential, forgery of user sessions, and direct
access to the controller database. |
| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, rdpsnd_server_recv_formats in channels/rdpsnd/server/rdpsnd_main.c frees context->client_formats on a malformed Client Audio Formats PDU without clearing the owning pointer or num_client_formats. An authenticated RDP client can trigger an error such as a cbSize larger than the remaining record, leave the dangling pointer in the server context, and cause rdpsnd_server_context_free to free the same allocation again at session teardown. This reliably terminates the server and can create allocator-dependent heap corruption. This issue is fixed in version 3.28.0. |
| Use of Externally-Controlled Format String vulnerability in RTI Connext Professional (Core Libraries) allows Format String Injection. This issue affects Connext Professional: from 7.5.0 before 7.7.0.1, from 7.3.0.10 before 7.3.1.6. |
| In the Linux kernel, the following vulnerability has been resolved:
i3c: master: Fix recursive locking during device registration
i3c_master_register_new_i3c_devs() registers newly discovered devices
while holding i3c_bus_normaluse_lock(), a down_read(). device_register()
can immediately probe the device, and probe callbacks typically invoke
I3C helpers that take i3c_bus_normaluse_lock() again, leading to a
recursive acquisition of the same rwsem. rwsems do not support recursive
read locking and can deadlock when a writer is waiting. See the
"Recursive read locks" section of Documentation/locking/lockdep-design.rst.
For example, with Intel LPSS I3C, LOCKDEP generates a WARNING like:
# echo intel-lpss-i3c.0 > /sys/bus/platform/drivers/mipi-i3c-hci/unbind
# echo intel-lpss-i3c.0 > /sys/bus/platform/drivers/mipi-i3c-hci/bind
WARNING: possible recursive locking detected
kworker/5:1/94 is trying to acquire lock:
ffff88811c810d78 (&i3cbus->lock){++++}-{4:4}, at: i3c_device_match_id+0x45/0x370
but task is already holding lock:
ffff88811c810d78 (&i3cbus->lock){++++}-{4:4}, at: i3c_master_reg_work_fn+0x21/0x5f0
Fix this by separating device creation from device registration.
Populate desc->dev under the maintenance lock, collect the devices that
still need registration into a local list, then release the lock before
calling device_register(). Finally retake the lock and clean up any
devices that failed to register.
Use the maintenance lock rather than the normal-use lock while adding
device objects. A write-side maintenance lock prevents readers from
observing a partially initialized desc->dev during initial device
population, or desc->dev disappearing if registration fails.
The local list requires a list node, so add a list node member to struct
i3c_device. |
