CVE-2026-92254: Watchdog Anti-Virus

Medium severity, CVSS 6.9. EPSS: 0.1% chance of exploitation in the next 30 days.

Missing Authorization in the IOCTL handlers of the wsdkd.sys kernel drivers in Watchdog WatchDog Antivirus 1.8.640 (driver versions 1.3.0.0 and earlier) on Microsoft Windows allows local, low-privileged attackers to delete arbitrary files with SYSTEM privileges, bypassing NTFS access controls and potentially disabling security products or destabilizing the operating system, via crafted IOCTL requests sent to the \Device\wsdk device.

Affected products

• Watchdog Anti-Virus: from 1.8.640, before 1.8.804 (fixed in 1.8.804)
