Description
A flaw was found in the Linux kernel's drm/xe/pt module. This vulnerability arises when the page-table walk framework provides a null pointer for unpopulated entries, and the xe_pt_zap_ptes_entry() function attempts to access this null pointer without prior validation. This improper handling can lead to a system crash, resulting in a Denial of Service (DoS).
