CVE-2025-58714
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 · uneditedImproper access control in Windows Ancillary Function Driver for WinSock 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 confidenceImproper access control in Windows Ancillary Function Driver for WinSock (AFD.sys) allows a local authenticated attacker to escalate privileges to SYSTEM level. The AFD driver handles Winsock communications in kernel mode, and the access control flaw enables a low-privileged user to gain elevated 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 installed Windows 10 versionRun 'winver' from command prompt or check System Properties. Look for the Build number (e.g., 19045).Affected if For Windows 10 1507 (Build 10240): version below 10.0.10240.21161. For Windows 10 1607 (Build 14393): version below 10.0.14393.8519. For Windows 10 1809 (Build 17763): version below 10.0.17763.7919. For Windows 10 21h2 (Build 19044): version below 10.0.19044.6456. For Windows 10 22h2 (Build 19045):
-
Check installed Windows 11 versionRun 'winver' from command prompt or check System Properties. Look for the Build number (e.g., 22621).Affected if For Windows 11 22h2 (Build 22621): version below 10.0.22621.6060. For Windows 11 23h2 (Build 22631): version 10.0.22631.6060 or below. For Windows 11 24h2 (Build 26100): version below 10.0.26100.6899.
-
Verify exact build number via command lineOpen Command Prompt or PowerShell and run 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' or 'winver /B' to get precise build information including the full version string.Affected if The full version string (such as 10.0.19045.1234) is lower than the fixed version for your specific Windows release.
You are affected if your Windows version build number falls below the fixed build number for your specific Windows release (10/11) and edition (1507, 1607, 1809, 21h2, 22h2, 22h2, 23h2, or 24h2).
