What to do

AI-suggested

A fix has been implemented in the Linux kernel to address this memory leak by improving the cleanup process in the atomic_destroy_state callback. Users should update to the fixed kernel version once available. No other mitigation steps are indicated.

Description

A memory leak vulnerability was identified and fixed in the Linux kernel's drm/atmel-hlcdc driver. The issue involved the atomic_destroy_state callback not properly freeing all drm_crtc_commit objects, causing slab memory to increase over time during graphics application usage. The fix involved using the __drm_atomic_helper_plane_destroy_state() function to release all unneeded objects.
