CVE-2026-13043

CriticalCVSS 9.3
Published: Translated: NVD NIST

Summary

The Kernel Memory Access Driver (PSKMAD) used by WatchGuard endpoint security products does not properly enforce authentication. A local, authenticated attacker can bypass the driver's access-control handshake and issue arbitrary privileged commands to the driver, resulting in disclosure of kernel and process memory.

Risk Assessment

An attacker with local access to the machine can read kernel and process memory, potentially exposing sensitive data, credentials, or enabling further privilege escalation.

Recommendation

Update WatchGuard products to a version containing the PSKMAD driver fix and restrict local access to machines running the endpoint security software.
