Description

A flaw was found in the Linux kernel's Intel Xe graphics driver (drm/xe). A local user could exploit this vulnerability by altering the memory state of a pinned graphics buffer object, causing the driver to unconditionally transfer pages between memory tracking pools. This issue triggers an integer underflow and corrupted memory accounting in the kernel shrinker, which may lead to system instability or a Denial of Service (DoS).
