Linux · Linux Kernel · CVE-2024-35786
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
The issue is related to a stale locked mutex in the `nouveau gem ioctl pushbuf` function. If `VM BIND` is enabled on the client, the legacy submission ioctl cannot be used. However, if a client attempts to use it regardless, it will return an error, and the client's mutex will remain unlocked, leading to a deadlock inside `nouveau drm postclose` or any other `nouveau` ioctl call. This can be exploited to cause a denial of service.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
