CVE-2024-47753

Local kernel crash via NULL framebuffer dereference

Published Oct 21, 2024 · Updated May 11, 2026

NULL pointer dereference in Linux 5.19 and later affected branches allows local users to crash the kernel through the MediaTek VP8 decoder. In vdec_vp8_slice_decode(), code applies container_of to a framebuffer pointer without first rejecting NULL, then dereferences the invalid result. A local low-privilege user must reach the stateless VP8 decode path; the documented consequence is a kernel crash, not data access or code execution.
