Summary
In the Linux kernel, the following vulnerability has been resolved: drm/xe: Prevent null pointer access in xe_migrate_copy xe_migrate_copy designed to copy content of TTM resources. When source resource is null, it will trigger a NULL pointer dereference in xe_migrate_copy. To avoid this situation, update lacks source flag to true for this case, the flag will trigger xe_migrate_clear rather than xe_migrate_copy.
