AI-suggested
A fix has been implemented in the Linux kernel to safely handle NULL ttm.resource pointers in bo_meminfo() by skipping purged buffer objects. Users should update to kernel versions that include this fix. Since this is a kernel-level vulnerability, applying the official kernel patches or upgrading to fixed kernel releases is the recommended remediation.
Description
A null pointer dereference (NPD) vulnerability exists in the Linux kernel's drm/xe component in the bo_meminfo() function. This occurs when a buffer object (BO) is purged and its ttm.resource is set to NULL, but the BO remains in the client's object list until userspace closes the GEM handle. Querying memory stats during this time leads to dereferencing a NULL pointer, causing potential crashes or instability. The issue has been fixed by adding checks to safely skip purged BOs in bo_meminfo().
