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.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
| Vendor | Product | Default status | Versions | ||||||
