Security readout for executives and security teams
CVE-2011-2491 is a Linux kernel availability flaw in NFS client lock handling. A local user could cause an affected system to hang. Business urgency is highest for older Linux hosts using NFS where multiple or untrusted local users have access. Exposure is likely limited to Linux systems running kernels before 3.0 that use NFS client functionality and allow local user access. Internet-facing remote exploitation is not indicated by the provided sources. Treat as a targeted availability risk for legacy Linux/NFS environments, not a broad remote compromise issue. Remediate during normal patch cycles unless affected systems support critical services or untrusted local users. Mitigation focus: Inventory Linux hosts with kernels earlier than 3.0.; Identify systems using NFS client locking functionality.; Apply vendor kernel updates that include the referenced upstream fix..
