Risk summary
Not in the CISA KEV catalog. EPSS exploit probability 54%. CVSS 7.8 (High).
This CVE is among the top half of tracked Microsoft CVEs by EPSS exploit probability.
Third in the run of Windows 11 26H1 DWM Core Library escalations, with the same Critical (CVSS 9.8) rating and 48 percent EPSS score as the others. Multiple parallel flaws in one compositor library give attackers fallback options, so the fleet is not safe until the update that fixes the whole set is applied. Only 26H1 x64 and ARM64 builds are affected.
Do this: Treat the 26H1 DWM group as a single patching unit and confirm compliance on every 26H1 device in one report.
