CVE-2026-68267
Description
A flaw was found in the drm/xe/rtp component of the Linux kernel. This vulnerability arises from the unconditional whitelisting of Output/Availability (OA) registers, which is a security violation. By default, these registers could be whitelisted after system events such as probe, graphics translation (gt) reset, resume, and engine reset. This improper whitelisting could allow a local attacker to gain unauthorized access to privileged OA registers, potentially leading to a security bypass or information disclosure.
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).
The following CVSS metrics and score provided are preliminary and subject to review.
