In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check null-initialized variables WHAT & HOW drrtiming and subvppipe are initialized to null and they are not always assigned new values. It is necessary to check for null before dereferencing. This fixes 2...

CVE-2024-49992

CVE-2024-49992 affects the Linux kernel DRM STM path. Specifically, ltdc_load() calls drm_crtc_init_with_planes(), drm_universal_plane_init(), and drm_encoder_init() with devm_kzalloc()-allocated resources, which can lead to use-after-free in CRTC/plane handling. Root cause: allocations not manag...
