CVE-2024-49992

Unspecified impact via DRM object use-after-free

Published Oct 21, 2024 · Updated Aug 5, 2026

Use-after-free in the Linux kernel STM display driver allows attackers to cause unspecified impact via unspecified vectors. In ltdc_load, DRM initialization retains CRTC, plane, encoder, and device pointers allocated with devm_kzalloc, whose device-managed lifetime can end before DRM releases those objects. Reachability requires the STM DRM driver and its display-controller initialization path; public upstream material identifies neither an attacker-controlled trigger nor a demonstrated consequence.
