CVE-2026-52949

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 backup failure can lead to an infinite LRU (Least Recently Used) walk within the ttm bo shrink() function. This occurs because the del bulk move operation is performed before the backup process. To resolve this, the operation must be moved to occur only after a successful backup, utilizing the ttm resource del bulk move unevictable() function, as the resource becomes unevictable once fully backed up.

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