Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/msm/dp: fixed memory corruption due to too many bridges. Added a missing sanity check on the bridge counter to prevent corruption of data beyond the fixed-sized bridge array, in case there are more than eight bridges...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/i915: Fixed the system suspension without fbdev being initialized. If fbdev is not initialized for some reason—in practice on platforms without a display—suspending fbdev should be skipped during system suspension. This...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fixed the issue where the unlock operation was not matched correctly for the DMUB HW lock in the HWSS fast path. Why The evaluation of whether we need to use the DMUB HW lock is different from the evaluation of...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/imagination: Fixed a deadlock in the soft reset sequence. The soft reset sequence is currently executed from the threaded IRQ handler. Therefore, it cannot call disableirq because it internally waits for the IRQ handlers—i.e....

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Validated user queue size constraints. Added validation to ensure that user queue sizes meet hardware requirements: - The size must be a power of two for efficient ring buffer wrapping. - The size must be at least...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/msm/a6xx: move preemptpreparepostamble after error check The call to preemptpreparepostamble is moved after verifying that preemptpostambleptr is valid. If preemptpostambleptr is NULL, dereferencing it in...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/xe: always keep track of remap prev/next During 3D workloads, users are reporting encountering the following issues: 413.361679 WARNING: drivers/gpu/drm/xe/xevm.c:1217 at vmBindIoctlOpsUnwind+0x1e2/0x2e0 xe, CPU7:...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Added outer runtime PM protection to xelivektest@xedmabuf. Any process using the kunit interface that performs memory accesses should receive its own outer runtime PM protection, since it does not use the standard driver...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fixed a DRM panic due to a null pointer when the driver does not support atomic operations. When the driver does not support atomic operations, fb uses plane-fb instead of plane-state-fb. Cherry-picked from commit...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/userq: Do not allow userspace to trivially trigger kernel warnings. Userspace can either deliberately pass in a too-small numfences value, or the required number can legitimately increase between the two calls to the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/xe: Do not allow eviction of BOs within the same VM in an array of VM binds An array of VM binds may potentially evict other buffer objects BOs within the same VM under certain conditions, which could lead to NULL pointer...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/plane: Fixed the return value of createinformatblob createinformatblob is supposed to return a valid pointer or an error; it should never return NULL. The caller will dereference the blob if there is no error, and thus will...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm: bridge: dwhdmi: fixed connector access for scdc The commit 5d844091f237 “drm/scdc-helper: Pimp SCDC debugs” changed the scdc interface to retrieve an i2c adapter from a connector. However, in the case of dwhdmi, the wrong...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/rockchip: vop2: Failure to properly handle cases where a primary plane for a video-port is missing. Each window of vop2 is usable by a specific set of video ports. Therefore, when binding vop2, we iterate through the list of...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fixed the null check on pipectx-planestate in updatedchubpdpp. This issue is similar to commit 6a057072ddd1 “drm/amd/display: Fixed a null pointer dereference on dcn20updatedchubpdpp. It involves the same functio...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/i915/ttm: Do not leak the ccs state. The kernel only manages the ccs state using lmem-only objects. However, the kernel should still take care to prevent leaking the CCS state from the previous user. Cherished from commit...
