CVE-2024-38547

Kernel crash via failed video-binary allocation

Published Jun 19, 2024 · Updated May 12, 2026

NULL pointer dereference in the Linux atomisp driver allows local users to crash the kernel after a video-binary allocation failure. load_video_binaries() leaves yuv_scaler_binary null when allocation fails, but cleanup passes its shared array slot to ia_css_binary_unload(). Reaching the flaw requires local access, the atomisp video path, and an allocation failure; the documented consequence is a kernel availability loss.
