CVE-2024-42500Network attack vector

Service interruption via undisclosed NFSv4 flaw

Published Sep 9, 2024 · Updated Mar 25, 2025

Denial of service in HPE HP-UX ONCplus before B.11.31.24 allows remote attackers to interrupt NFSv4 services. HPE has not disclosed the affected NFSv4 request path, code locus, or the operation performed incorrectly on untrusted network input. Unauthenticated network reachability to the NFSv4 service is sufficient, and the documented consequence is service interruption rather than data disclosure.
