CVE-2026-43269
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
drm/atmel-hlcdc: fix memory leak from the atomic_destroy_state callback
After several commits, the slab memory increases. Some drm_crtc_commit objects are not freed. The atomic_destroy_state callback only put the framebuffer. Use the __drm_atomic_helper_plane_destroy_state() function to put all the objects that are no longer needed.
It has been seen after hours of usage of a graphics application or using kmemleak:
