CVE-2026-52965

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

Description An issue exists in the drm/ttm component where a failure in ttm tt swapout() can lead to an infinite loop during the LRU (Least Recently Used) list walk. This occurs because ttm resource move to lru tail() places the resource at the tail of the LRU list, positioning it in front of the walk cursor's hitch node. Consequently, the list for each entry continue() function repeatedly finds the same resource. To resolve this, the removal of bulk move membership is deferred to the success path, and a new function ttm resource del bulk move unevictable() is introduced to bypass the !ttm resource unevictable() guard that would otherwise incorrectly skip removal when TTM TT FLAG SWAPPED is set.

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