CVE-2026-52976

A flaw was found in the Linux kernel. Specifically, within the `drm/xe` graphics driver, two error handling issues in the `xe_exec_queue_create_ioctl()` function could lead to memory corruption. This could result in a dangling pointer or a use-after-free vulnerability. A local attacker could potentially exploit these issues to cause a system crash (denial of service) or gain elevated privileges.
