CVE-2026-53066

A flaw was found in the Linux kernel's drm/sun4i backend component. This vulnerability occurs because the drmatomicgetplanestate function can return an error pointer, which is not properly checked before being dereferenced. An attacker could potentially trigger this unchecked dereference, leading...

CVE-2026-53066

In the Linux kernel, the drm/sun4i backend fixed an error pointer dereference: drm_atomic_get_plane_state() could return an error pointer and was not checked in sun4i_backend_atomic_check(), risking a dereference of plane_state. The issue is resolved by adding an error pointer check. Connected re...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: drm/atmel-hlcdc: fixed the issue where “drmcrtccommit” was used after release. The atmelhlcdcplaneatomicduplicatestate callback was copying the atmelhlcdcplane state structure without properly duplicating the drmplanestate...

PT-2026-51960

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An error pointer dereference exists in the drm/sun4i backend. The function drm atomic get plane state can return an error pointer that is not properly checked before use. This can lead t...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/sysfb: Do not dereference a NULL pointer during plane reset. The plane state in drmgemresetshadowplane can be NULL. Do not dereference that pointer; instead, pass NULL to the other plane-reset helpers. Clear plane-state to NU...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/vmwgfx: Unmap the surface before resetting it on a plane state Switching to a new plane state requires unreferencing of all held surfaces. In the work required for mob cursors, the mapped surfaces started being cached, but...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/msm/mdp5: Do not leak some plane state. Apparently, no one noticed that the mdp5 plane states are being leaked quite severely. This issue was addressed since we introduced the planestate-commit refcount mechanism a few years...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/i915: Unlink NV12 planes earlier. The unlinknv12plane function will corrupt parts of the plane’s state, potentially those that have already been set by planeatomiccheck. Therefore, we must ensure that these two functions are...

In the Linux kernel, the following vulnerability has been resolved: drm/atmel-hlcdc: fix use-after-free of drmcrtccommit after release The atmelhlcdcplaneatomicduplicatestate callback was copying the atmelhlcdcplane state structure without properly duplicating the drmplanestate. In particular,...

CVE-2026-43236

A flaw was found in the Linux kernel's drm/atmel-hlcdc component. An issue in the atmelhlcdcplaneatomicduplicatestate callback, which incorrectly duplicates the drmplanestate, can lead to a use-after-free vulnerability. This can be triggered when a device node is closed and re-opened while anothe...
