The nfs_permission function in fs/nfs/dir.c in the NFS client implementation in the Linux kernel 2.6.29.3 and earlier, when atomic_open is available, does not check execute (aka EXEC or MAY_EXEC) permission bits, which allows local users to bypass permissions and execute files, as demonstrated by files on an NFSv4 fileserver.

Security readout for executives and security teams

This older Linux kernel NFS client flaw can let a local user run a file from an NFS share even when execute permission should block it. The business risk is concentrated on systems that allow local users and mount NFS, especially NFSv4. No active exploitation is stated in the provided sources. Exposure is likely limited to legacy Linux systems running affected kernels as NFS clients, with local user access and NFS-mounted filesystems. The source bundle does not provide precise CPEs or distribution package version ranges. Treat as a targeted legacy Linux exposure issue. Prioritize remediation where NFS shares protect sensitive tools, scripts, or data by execute permissions and where local users are present. Mitigation focus: Review Debian, Red Hat, Mandriva, VMware, and other vendor advisories for fixed kernel packages.; Update affected Linux kernels using supported vendor security updates.; Prioritize NFS client hosts with local shell or multi-user access..
