This CVE is among the top half of tracked Microsoft CVEs by EPSS exploit probability.
This is an elevation of privilege flaw in the Windows Secure Kernel Mode, the isolated component that underpins virtualization based security features like Credential Guard, so a successful exploit undermines the very boundary meant to protect secrets. It affects specific Windows 11 builds including 25H2 x64 and the ARM64 24H2 and 26H1 releases, meaning both current desktop and ARM based fleets are in scope. It is rated Severity High with a CVSS score of 7.0, is not in CISA KEV, and has no known ransomware use, so this is a patch on a normal cadence rather than an emergency.
Do this: Deploy the Windows 11 cumulative update covering CVE-2026-50392 to your 25H2 x64 and ARM64 24H2 and 26H1 systems through your standard ring based rollout.
