CVE-2025-38743

Local privilege escalation via incorrect buffer length

Published Aug 21, 2025 · Updated Feb 26, 2026

Buffer access with an incorrect length in Dell iDRAC Service Module before 6.0.3.0 allows local users to execute code with elevated privileges. Dell identifies the flaw only as an incorrect length used for a buffer access and has not disclosed the affected component, function, or input path. Exploitation requires low-privileged local access and can compromise host confidentiality, integrity, and availability through elevated code execution.
