Risk summary
Not in the CISA KEV catalog. EPSS exploit probability 6.0%. CVSS 7.0 (High).
This CVE is among the lower half of tracked Microsoft CVEs by EPSS exploit probability.
VBS enclaves are meant to be a hardware-backed trust boundary that isolates sensitive code even from a compromised kernel, so an elevation of privilege bug there, rated Critical at 9.9, is a meaningful erosion of that isolation guarantee. It affects Windows 11 25H2 and the older Windows 11 22H2 on ARM64, with a 6 percent EPSS score. No confirmed exploitation or ransomware activity.
Do this: Patch any system relying on VBS enclaves for sensitive workloads, such as credential guard or DRM-protected applications, without delay.
