CVE-2026-52949 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/ttm: Fix ttm_bo_shrink() infinite LRU walk on backup failure Apply the same fix as b2ed01e7ad ("drm/ttm: Fix ttm_bo_swapout() infinite LRU walk on swapout failure") to the ttm_bo_shrink() path. Move del_bulk_move from before the backup to after success only, using ttm_resource_del_bulk_move_unevictable() since the resource is now unevictable once fully backed up.
A vulnerability in the Linux kernel's Direct Rendering Manager (DRM) component, specifically within the Translation Table Maps (TTM) memory management, has been addressed. The issue involved an infinite walk of the Least Recently Used (LRU) list during the process of shrinking buffer objects, which could occur if a backup operation failed. This vulnerability was present in versions of the Linux kernel through 6.15.
Users can upgrade to the latest version of the Linux kernel to address this vulnerability. The patched version is included in the official Linux kernel stable releases.
