CVE-2026-52976
Description
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.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
