AI-suggested

A fix for this vulnerability has been implemented in the affected Linux kernel versions. Users should update to the patched versions listed or later to remediate the issue. No additional mitigation actions are indicated.

Description

A vulnerability in the Linux kernel's dma-fence subsystem could cause null pointer dereferences in certain tracepoints related to fence operations. This issue has been fixed by adjusting the tracepoint handling to safely access fence operation pointers and by introducing a new tracepoint class to avoid dereferencing null pointers after fence signaling.
