Description
A flaw was found in the Linux kernel's Direct Rendering Manager (DRM) subsystem, specifically within the xe/vm module. A local user could exploit improper error handling when clearing the scratch_pt pointer in the xe_vm_free_scratch() function. This could lead to a dereference of an error pointer during cleanup, potentially causing a system crash and resulting in a denial of service (DoS).
