Local privilege escalation via TOCTOU race
Published Aug 19, 2026 · Updated Aug 20, 2026
Race condition in Dell Command Update before 5.7.1 allows local users to gain elevated privileges via a time-of-check/time-of-use flaw. Dell's CNA record classifies the issue as CWE-367 but does not identify the raced file, directory, or update step, so the vulnerable check-use boundary is not public. Exploitation requires local low-privileged access and user interaction, and the published impact is privilege escalation on affected Windows client systems.
