It is attacked with local access, in device firmware.

Am I affected by CVE-2026-20756?

Check whether you run Intel Arc B-series graphics cards, Intel Arc Graphics Driver, Intel Arc Pro Graphics Driver or one of the others listed at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

CVE-2026-20756: Intel Graphics Driver privilege escalation in installer permissions

CVE-2026-20756 · Severity: info · Published 2026-11-10

Intel Graphics Driver installers contain incorrect default file permissions that allow unprivileged local users to escalate their privileges and gain full system control. An attacker with local access and an authenticated user session can exploit installer components to read, modify, or delete sensitive system files. Successful exploitation requires the user to trigger the installer update process, but once exploited grants complete compromise of the affected system.

Technical details

The vulnerability exists in Intel Graphics Driver installers (Ring 3: User Applications) which set incorrect default permissions on installer-related files. A low-privileged authenticated user can exploit insecure inherited permissions or uncontrolled search paths to achieve local code execution and privilege escalation. The attack requires local access, active user interaction (installer execution), and high complexity, but impacts system confidentiality, integrity, and availability.
