CVE-2024-57980

Kernel memory corruption via dangling status pointer

Published Feb 27, 2025 · Updated May 11, 2026

A double free in Linux uvcvideo allows local users to corrupt kernel memory when status interrupt-URB allocation fails. uvc_status_init frees dev->status after int_urb allocation fails but leaves the dangling pointer for uvc_status_cleanup to free again. Reachability requires the uvcvideo status-initialization error path, and the second free exposes the host to a kernel crash or altered kernel execution.
