DescriptionCVE.org

Out-of-bounds read in Windows Kernel allows an authorized attacker to elevate privileges locally.

AnalysisAI

Local privilege escalation in the Microsoft Windows Kernel lets an already-authenticated attacker read memory outside allocated bounds (CWE-125) and leverage it to elevate to SYSTEM across a broad range of client and server builds (Windows 10 1809 through Windows 11 26H1, Windows Server 2019 through 2025). Microsoft rates it CVSS 8.8 with a changed scope, and a vendor patch is available; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.
