CVE-2025-50168
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAccess of resource using incompatible type ('type confusion') in Windows Win32K - ICOMP allows an authorized attacker to elevate privileges locally.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA type confusion vulnerability in the Windows Win32K subsystem's ICOMP component allows a locally authorized attacker to exploit improper type handling to elevate privileges from a low-privileged context to SYSTEM level access.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Windows build versionOpen Command Prompt or PowerShell and run: `winver` or `systeminfo | findstr /B /C:"OS Version"` or `[System.Environment]::OSVersion.Version`Affected if The displayed build number is lower than 10.0.22621.5768 (for 22h2), 10.0.22631.5768 (for 23h2), 10.0.26100.4851 (for 24h2), 10.0.25398.1791 (for Server 2022 23h2), or 10.0.26100.4851 (for Server 2025)
-
Confirm Windows edition matches affected product lineRun `systeminfo | findstr /C:"OS Name"` and verify the system is one of: Windows 11 22h2, Windows 11 23h2, Windows 11 24h2, Windows Server 2022, or Windows Server 2025Affected if The edition is Windows 11 or Windows Server and the build version falls within the affected ranges in step 1
-
Verify local user contextRun `whoami /groups` to confirm the current user is a low-privileged user (not already running as Administrator or SYSTEM)Affected if The current user is in the Users group or equivalent low-privilege context and the Windows version is vulnerable per steps 1-2
The system is affected if it runs a Windows 11 or Windows Server version within the specified build ranges AND the attacker has local low-privileged access to attempt privilege escalation via the Win32K ICOMP component.
