CVE-2026-52951

A flaw was found in the Linux kernel's drm/xe/dma-buf subsystem. This vulnerability involves race conditions when handling the invalidate_mappings hook, particularly during buffer object initialization and attachment. An attacker, by triggering specific sequences of operations, could exploit these races to cause a Use-After-Free (UAF) condition or a NULL pointer dereference. This could lead to system instability and crashes, resulting in a Denial of Service (DoS).
