CVE-2026-13043

9.3 critical exploit SSVC exploitation: none Analyzed
NVD · CVE.org

A missing authentication vulnerability in the Kernel Memory Access Driver (PSKMAD) used by WatchGuard endpoint security products allows a local, authenticated attacker to bypass the driver's access-control handshake and issue arbitrary privileged commands to the driver, resulting in disclosure of kernel and process memory.

Fix

Public exploits 1

Each line links to the index that lists it, never to exploit code. Exploit-DB's "verified" and a Metasploit rank of good or better count as verified; a PoC-in-GitHub entry is a repository's claim.

Patch, vendor advisory and mitigation references on NVD 1

Every line above is quoted from NVD, CISA, Microsoft, the vendor's own advisory or DISA; nothing is generated.
