There is no public exploit identified at time of analysis, and it is not listed in CISA KEV; a vendor patch is available.
Local privilege escalation in the Windows Ancillary Function Driver for WinSock (afd.sys) lets an already-authenticated user execute code in kernel context and gain SYSTEM-level rights, affecting a broad Windows client and server range from Windows Server 2012 through Windows 11 25H2/26H1 and Server 2025. The flaw is a CWE-416 use-after-free that yields total technical impact (C:H/I:H/A:H). Microsoft has shipped a patch; there is no public exploit identified at time of analysis and CISA's SSVC framework lists exploitation as none, with a low EPSS of 0.25% (16th percentile).
