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

Description A flaw exists in the Linux kernel’s DRM/TTM subsystem related to bulk move corruption when adding an entry. Specifically, when a resource is the first in a bulk move range and is added again, it moves to the tail of the list, corrupting the list because the first pointer is not moved. This can lead to a null pointer dereference in the ttm lru bulk move del() function.

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