CVE-2024-29937
Published: 11 April 2024
Summary
CVE-2024-29937 is a critical-severity Code Injection (CWE-94) vulnerability in Freebsd Freebsd. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 10.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2024-29937 is a remote code execution vulnerability in the NFS implementation within a BSD-derived codebase, affecting OpenBSD through version 7.4 and FreeBSD through 14.0-RELEASE. The flaw, tracked under CWE-94, permits arbitrary code execution through a mechanism unrelated to memory corruption and carries a CVSS 3.1 score of 9.8 reflecting network-accessible attack complexity that requires no privileges or user interaction.
Remote unauthenticated attackers can exploit the issue over the network to achieve full code execution on affected systems running the vulnerable NFS components. The published description indicates the bug enables this outcome directly via crafted NFS traffic without relying on memory-safety violations.
The EPSS score for the CVE rose from a low baseline to a peak of 0.0808 before receding to the current value of 0.0436, indicating measurable post-disclosure interest. Public references consist primarily of conference presentations and discussion threads rather than vendor advisories, with no mitigation or patch details supplied in the available sources.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
