CVE-2026-53201

A flaw was found in the Linux kernel's drm/xe graphics driver. An optimization intended to skip execution queue schedule toggling during GPU suspend could bypass a critical GuC suspend operation. This bypass prevents the GPU from properly flushing Translation Lookaside Buffer (TLB) entries for invalidated user memory areas, particularly in specific virtual memory modes. A local attacker could exploit this to cause missed TLB invalidations and page faults, potentially leading to information disclosure or a denial of service.
