Microsoft has released a patch; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Local privilege escalation in the Windows Kernel lets an already-authenticated attacker corrupt kernel memory via a use-after-free (CWE-416) and gain full control of the host. The CVSS 3.1 vector (AV:L/PR:L, scope-changed with C:H/I:H/A:H) reflects a low-privileged local user escalating to SYSTEM-level compromise across a broad range of Windows 10, Windows 11, and Windows Server builds. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but Microsoft has released a patch.
