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;...
