GHSA-W36H-73V6-WG8Q

Vulnerability from github – Published: 2024-05-17 15:31 – Updated: 2025-01-10 18:31

Details

In the Linux kernel, the following vulnerability has been resolved:

drm/nouveau: fix stale locked mutex in nouveau_gem_ioctl_pushbuf

If VM_BIND is enabled on the client the legacy submission ioctl can't be used, however if a client tries to do so regardless it will return an error. In this case the clients mutex remained unlocked leading to a deadlock inside nouveau_drm_postclose or any other nouveau ioctl call.

Severity ?

5.5 (Medium)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
