CVE-2022-37937Network attack vector

Unauthenticated memory corruption via undisclosed input

Published Feb 22, 2023 · Updated Mar 17, 2025

Memory corruption in HPE Serviceguard for Linux before A.12.80.05 allows remote attackers to cause unspecified impact. HPE has not published the affected component, the input that reaches it, or the memory operation that corrupts data outside its intended bounds. Network access without authentication or user interaction is sufficient, but public evidence does not define whether exploitation causes code execution, data access, or a service crash.
