CVE-2024-29937Network attack vector

Unauthenticated remote code execution

Published Mar 21, 2024 · Updated Mar 13, 2025

Code injection in NFS in OpenBSD 7.4 and earlier and FreeBSD 14.0-RELEASE and earlier allows remote attackers to execute arbitrary code. The published record identifies only a non-memory-corruption bug in the BSD-derived NFS implementation and does not disclose the erroneous operation. An unauthenticated attacker with network access to a running NFS service can execute code with the service's privileges; no user interaction is required.
