- The MSRC advisory has not been retrieved, so the matching KB numbers are unknown.
Workaround
Unknown. No vendor workaround has been documented.
Exploitation
- CISA SSVC assessment: exploitation none, automatable yes, technical impact total.
- No public exploitation or proof-of-concept is known at the time of writing.
Our recommendation
- Inventory all Windows 10, Windows 11 and Windows Server systems and compare their build numbers with the affected ranges above.
- Install the Microsoft security update for each affected system as soon as it is available, and verify the resulting build number.
- Restrict untrusted images and files from email and web downloads until patched, and run users without local administrator rights.
- Monitor for exploitation and check the MSRC advisory and CISA KEV again within 24 to 48 hours.
