CVE-2024-49992 is a high-severity use-after-free vulnerability in the Linux kernel's drm/stm component. It involves improper use of memory allocation functions in drm_crtc_init_with_planes(), drm_universal_plane_init(), and drm_encoder_init() when called with parameters allocated via devm_kzalloc(), leading to potential use-after-free conditions. The issue was identified by the Linux Verification Center and resolved by ensuring allocations are managed by the DRM framework.
