CVE-2026-52950

A flaw was found in the Linux kernel, specifically within the drm/xe/dma-buf component. This Use-After-Free (UAF) vulnerability occurs due to an issue in a retry loop, where a buffer object is prematurely freed on error. An attacker could potentially exploit this to cause memory corruption, leading to system instability or, in some cases, arbitrary code execution.
