The __nfs4_get_acl_uncached function in fs/nfs/nfs4proc.c in the NFSv4 implementation in the Linux kernel before 3.3.2 uses an incorrect length variable during a copy operation, which allows remote NFS servers to cause a denial of service (OOPS) by sending an excessive number of bitmap words in an FATTR4_ACL reply. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-4131.

Security readout for executives and security teams

A malicious or compromised NFSv4 server could crash a vulnerable Linux client kernel by sending an oversized ACL-related reply. The business impact is denial of service on systems that mount NFSv4 shares from an untrusted or compromised server. The source bundle does not show active exploitation or a CVSS score. Exposure is most likely on Linux systems using NFSv4 client mounts to remote servers, especially untrusted, partner-managed, or potentially compromised NFS servers. The bundle does not identify complete distribution version ranges beyond Linux kernel before 3.3.2 and vendor advisories. Treat as a targeted availability risk, not a broad internet emergency. Patch or isolate affected NFSv4 clients during normal vulnerability cycles, faster where NFS servers are externally managed or less trusted. Mitigation focus: Apply a vendor kernel update that includes the upstream fix.; For upstream kernels, move beyond Linux 3.3.2 or confirm the fix is backported.; Prioritize systems mounting NFSv4 shares from less-trusted servers..
