Security readout for executives and security teams
A flaw in the network file-locking service (rpc.lockd) shipped with Red Hat Linux 6.1 and 6.2 lets a remote attacker crash that service by sending a malformed request. The impact is a denial of service against file-locking, which can disrupt applications that rely on NFS locking. This is a legacy issue from 2000 that should only surface on very old, unmaintained systems. Exposure is limited to systems still running Red Hat Linux 6.1/6.2 (both long end-of-life) with rpc.lockd reachable from untrusted networks. Modern, supported Linux distributions are not identified as affected in the bundle. Low priority for modern estates. Prioritize only if legacy Red Hat Linux 6.x systems remain in service; those hosts are past end-of-life and represent broader risk beyond this single CVE, so plan decommissioning or isolation rather than a targeted fix. Mitigation focus: Retire or upgrade any Red Hat Linux 6.1/6.2 hosts to a currently supported distribution.; Restrict access to portmap and rpc.lockd (typically UDP/TCP 111 and the lockd port) at the network boundary.; If NFS locking is not required, disable rpc.lockd on affected hosts..
