| In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Unreserve bo if queue update failed
Error handling path should unreserve bo then return failed.
(cherry picked from commit c24afed7de9ecce341825d8ab55a43a254348b33) |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix use-after-free by using call_rcu() for oplock_info
ksmbd currently frees oplock_info immediately using kfree(), even
though it is accessed under RCU read-side critical sections in places
like opinfo_get() and proc_show_files().
Since there is no RCU grace period delay between nullifying the pointer
and freeing the memory, a reader can still access oplock_info
structure after it has been freed. This can leads to a use-after-free
especially in opinfo_get() where atomic_inc_not_zero() is called on
already freed memory.
Fix this by switching to deferred freeing using call_rcu(). |
| In the Linux kernel, the following vulnerability has been resolved:
gpib: lpvo_usb: fix memory leak on disconnect
The driver iterates over the registered USB interfaces during GPIB
attach and takes a reference to their USB devices until a match is
found. These references are never released which leads to a memory leak
when devices are disconnected.
Fix the leak by dropping the unnecessary references. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: gyro: mpu3050: Move iio_device_register() to correct location
iio_device_register() should be at the end of the probe function to
prevent race conditions.
Place iio_device_register() at the end of the probe function and place
iio_device_unregister() accordingly. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: gyro: mpu3050: Fix irq resource leak
The interrupt handler is setup but only a few lines down if
iio_trigger_register() fails the function returns without properly
releasing the handler.
Add cleanup goto to resolve resource leak.
Detected by Smatch:
drivers/iio/gyro/mpu3050-core.c:1128 mpu3050_trigger_probe() warn:
'irq' from request_threaded_irq() not released on lines: 1124. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: gyro: mpu3050: Fix incorrect free_irq() variable
The handler for the IRQ part of this driver is mpu3050->trig but,
in the teardown free_irq() is called with handler mpu3050.
Use correct IRQ handler when calling free_irq(). |
| In the Linux kernel, the following vulnerability has been resolved:
iio: imu: st_lsm6dsx: Set buffer sampling frequency for accelerometer only
The st_lsm6dsx_hwfifo_odr_store() function, which is called when userspace
writes the buffer sampling frequency sysfs attribute, calls
st_lsm6dsx_check_odr(), which accesses the odr_table array at index
`sensor->id`; since this array is only 2 entries long, an access for any
sensor type other than accelerometer or gyroscope is an out-of-bounds
access.
The motivation for being able to set a buffer frequency different from the
sensor sampling frequency is to support use cases that need accurate event
detection (which requires a high sampling frequency) while retrieving
sensor data at low frequency. Since all the supported event types are
generated from acceleration data only, do not create the buffer sampling
frequency attribute for sensor types other than the accelerometer. |
| In the Linux kernel, the following vulnerability has been resolved:
pstore: ram_core: fix incorrect success return when vmap() fails
In persistent_ram_vmap(), vmap() may return NULL on failure.
If offset is non-zero, adding offset_in_page(start) causes the function
to return a non-NULL pointer even though the mapping failed.
persistent_ram_buffer_map() therefore incorrectly returns success.
Subsequent access to prz->buffer may dereference an invalid address
and cause crashes.
Add proper NULL checking for vmap() failures. |
| In the Linux kernel, the following vulnerability has been resolved:
nvme-pci: Fix race bug in nvme_poll_irqdisable()
In the following scenario, pdev can be disabled between (1) and (3) by
(2). This sets pdev->msix_enabled = 0. Then, pci_irq_vector() will
return MSI-X IRQ(>15) for (1) whereas return INTx IRQ(<=15) for (2).
This causes IRQ warning because it tries to enable INTx IRQ that has
never been disabled before.
To fix this, save IRQ number into a local variable and ensure
disable_irq() and enable_irq() operate on the same IRQ number. Even if
pci_free_irq_vectors() frees the IRQ concurrently, disable_irq() and
enable_irq() on a stale IRQ number is still valid and safe, and the
depth accounting reamins balanced.
task 1:
nvme_poll_irqdisable()
disable_irq(pci_irq_vector(pdev, nvmeq->cq_vector)) ...(1)
enable_irq(pci_irq_vector(pdev, nvmeq->cq_vector)) ...(3)
task 2:
nvme_reset_work()
nvme_dev_disable()
pdev->msix_enable = 0; ...(2)

| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nfnetlink_queue: fix entry leak in bridge verdict error path
nfqnl_recv_verdict() calls find_dequeue_entry() to remove the queue
entry from the queue data structures, taking ownership of the entry.
For PF_BRIDGE packets, it then calls nfqa_parse_bridge() to parse VLAN
attributes. If nfqa_parse_bridge() returns an error (e.g. NFQA_VLAN
present but NFQA_VLAN_TCI missing), the function returns immediately
without freeing the dequeued entry or its sk_buff.
This leaks the nf_queue_entry, its associated sk_buff, and all held
references (net_device refcounts, struct net refcount). Repeated
triggering exhausts kernel memory.
Fix this by dropping the entry via nfqnl_reinject() with NF_DROP verdict
on the error path, consistent with other error handling in this file. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: Fix for duplicate device in netdev hooks
When handling NETDEV_REGISTER notification, duplicate device
registration must be avoided since the device may have been added by
nft_netdev_hook_alloc() already when creating the hook. |
| In the Linux kernel, the following vulnerability has been resolved:
spi: rockchip-sfc: Fix double-free in remove() callback
The driver uses devm_spi_register_controller() for registration, which
automatically unregisters the controller via devm cleanup when the
device is removed. The manual call to spi_unregister_controller() in
the remove() callback can lead to a double-free.
And to make sure controller is unregistered before DMA buffer is
unmapped, switch to use spi_register_controller() in probe(). |
| In the Linux kernel, the following vulnerability has been resolved:
spi: amlogic: spifc-a4: Fix DMA mapping error handling
Fix three bugs in aml_sfc_dma_buffer_setup() error paths:
1. Unnecessary goto: When the first DMA mapping (sfc->daddr) fails,
nothing needs cleanup. Use direct return instead of goto.
2. Double-unmap bug: When info DMA mapping failed, the code would
unmap sfc->daddr inline, then fall through to out_map_data which
would unmap it again, causing a double-unmap.
3. Wrong unmap size: The out_map_info label used datalen instead of
infolen when unmapping sfc->iaddr, which could lead to incorrect
DMA sync behavior. |
| In the Linux kernel, the following vulnerability has been resolved:
net: spacemit: Fix error handling in emac_tx_mem_map()
The DMA mappings were leaked on mapping error. Free them with the
existing emac_free_tx_buf() function. |
| In the Linux kernel, the following vulnerability has been resolved:

| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: add upper bound check on user inputs in signal ioctl
Huge input values in amdgpu_userq_signal_ioctl can lead to a OOM and
could be exploited.
So check these input value against AMDGPU_USERQ_MAX_HANDLES
which is big enough value for genuine use cases and could
potentially avoid OOM.

| In the Linux kernel, the following vulnerability has been resolved:
wifi: wl1251: validate packet IDs before indexing tx_frames
wl1251_tx_packet_cb() uses the firmware completion ID directly to index
the fixed 16-entry wl->tx_frames[] array. The ID is a raw u8 from the
completion block, and the callback does not currently verify that it
fits the array before dereferencing it.
Reject completion IDs that fall outside wl->tx_frames[] and keep the
existing NULL check in the same guard. This keeps the fix local to the
trust boundary and avoids touching the rest of the completion flow. |
| The CloudStack Backup plugin has an improper authorization logic in versions 4.21.0.0 and 4.22.0.0. Anyone with authenticated user-account access in CloudStack 4.21.0.0+ environments, where this plugin is enabled and has access to specific APIs can list backups from any account in the environment. This vulnerability does not allow them to see the contents of the backup.
Users are recommended to upgrade to version 4.22.0.1, which fixes the issue. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: mixer: oss: Add card disconnect checkpoints
ALSA OSS mixer layer calls the kcontrol ops rather individually, and
pending calls might be not always caught at disconnecting the device.
For avoiding the potential UAF scenarios, add sanity checks of the
card disconnection at each entry point of OSS mixer accesses. The
rwsem is taken just before that check, hence the rest context should
be covered by that properly. |
