CVE-2024-35786

Local denial of service via unreleased client mutex

Published May 17, 2024 · Updated May 11, 2026

Denial of service in the Linux nouveau DRM driver allows local users to deadlock GPU client operations via a legacy push-buffer ioctl. nouveau_gem_ioctl_pushbuf returns -ENOSYS directly when a VM_BIND client invokes the legacy ioctl, bypassing nouveau_abi16_put and leaving the client mutex locked. Local users must have access to a nouveau DRM device and a VM_BIND-enabled client; triggering the error blocks post-close handling and subsequent nouveau ioctls.
