Multiple buffer overflows in fs/nfsd/nfs4xdr.c in the XDR implementation in the NFS server in the Linux kernel before 2.6.34-rc6 allow remote attackers to cause a denial of service (panic) or possibly execute arbitrary code via a crafted NFSv4 compound WRITE request, related to the read_buf and nfsd4_decode_compound functions.

Security readout for executives and security teams

This flaw affects old Linux NFS servers. A remote attacker who can reach NFSv4 could send a malformed write request that may crash the kernel and possibly execute code. Business risk is concentrated in legacy Linux systems still running vulnerable kernels or vendor packages. Exposure is most likely on legacy Linux servers providing NFSv4, especially systems that missed 2010-era kernel vendor updates. Modern supported distributions are unlikely to be vulnerable if fully patched. Prioritize remediation for any internet- or partner-reachable NFSv4 server and any unsupported legacy Linux estate. For fully supported, patched systems, treat this as a legacy hygiene verification item. Mitigation focus: Apply relevant vendor kernel security updates or supported replacement packages.; Confirm the running kernel includes the upstream fix or a vendor backport.; If updating is delayed, follow vendor guidance and reduce NFSv4 exposure..
