The fix

We hold no Microsoft remediation data for CVE-2026-92254, which normally means it is not a Windows CVE. For non-Microsoft software the fix is the vendor's own updated release, and the affected versions are listed below.

What it is

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.
