Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

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...

The vulnerability of the DRM/Atmel-HLCDC components in the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the DRM/Atmel-HLCDC components in the Linux operating system’s kernel is related to improper memory release before removing the last reference. Exploiting this vulnerability can allow an attacker to cause a service failure...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

SUSE CVE-2026-43269

In the Linux kernel, the following vulnerability has been resolved: drm/atmel-hlcdc: fix memory leak from the atomicdestroystate callback After several commits, the slab memory increases. Some drmcrtccommit objects are not freed. The atomicdestroystate callback only put the framebuffer. Use the...

CVE-2026-43269

A flaw was found in the Linux kernel's drm/atmel-hlcdc component. The atomicdestroystate callback in the drm/atmel-hlcdc driver does not correctly release all allocated objects, specifically drmcrtccommit objects. This oversight leads to a memory leak, where system memory gradually increases. Ove...

CVE-2026-43269

The CVE-2026-43269 issue affects the Linux kernel drm/atmel-hlcdc driver, where the atomic_destroy_state path failed to free all allocated objects (notably drm_crtc_commit), causing a memory leak observed via kmemleak. The root cause is that only the framebuffer was freed by atomic_destroy_state;...
