Local privilege escalation via ReFS out-of-bounds read
Published Mar 14, 2023 · Updated Jan 1, 2025
Out-of-bounds read in Windows 11 22H2 ReFS before 10.0.22621.1413 allows local users to elevate privileges on an affected system. ReFS reads beyond a memory buffer boundary, but Microsoft has not disclosed the affected routine, input structure, or trigger. Exploitation requires low-privileged local access and can compromise confidentiality, integrity, and availability at system scope.
