CVE-2024-46867

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A real deadlock as well as a sleeping in atomic bug has been identified in the Linux kernel, specifically in the drm/xe/client module. The issue arises when the bo put happens to be the last ref, causing bo destruction to attempt to grab the same spinlock and sleeping locks. This is resolved by dropping the ref using xe bo put deferred() and moving the final commit outside of the lock. The process of dropping the lock around the put is complex due to the potential for the bo to go out of scope and delete itself from the list, making navigation to the next list entry challenging.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
