CVE-2025-40110

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

Description The Linux kernel contains a flaw within the drm/vmwgfx subsystem related to cursor snooping. The issue arises from a missing check for resource existence before attempting to use the cursor snooper, potentially leading to a null pointer access. The vmw cmd res check function permits invalid identifiers, and functions handling surfaces may not be able to manage null objects. This fix validates both the identifier and the resource's existence before proceeding with snooping operations, addressing the unchecked null pointer reference.

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