SYSTEM privilege escalation via numeric conversion
Published Mar 11, 2025 · Updated Feb 13, 2026
Out-of-bounds read in the Microsoft Windows Common Log File System Driver allows local users to elevate privileges to SYSTEM. The driver converts a numeric value incorrectly during CLFS data handling, causing an out-of-bounds read; Microsoft has not disclosed the affected routine or field. Successful exploitation requires prior local low-privilege access and yields SYSTEM-level control over the affected Windows host.
