Information disclosure via restore-agent stack overflow
Published Sep 3, 2026 · Updated Sep 3, 2026
Stack buffer overflow in the file-level restore agent in Dell PowerProtect Data Manager 20.2.0.0 and earlier allows attackers to disclose information. Dell has not published the affected function, input, or incorrect copy operation within the agent. The advisory describes a highly privileged remote attacker, while its CVSS vector instead requires local low-privileged access; the disclosed consequence is limited to information exposure.
