CVE-2026-80126Network attack vector

Authenticated filesystem disruption via improper locking

Published Sep 7, 2026 · Updated Sep 8, 2026

Improper locking in Dell SCG 5.0 Appliance before 5.36.00.16 and Application before 5.36.00.00 allows remote authenticated users to interrupt filesystem availability. Dell has not published the affected component, protected resource, or incorrect lock operation. Low-privileged remote access is sufficient, and the published assessment supports availability loss but no reading or modification of filesystem data.
