Race condition in the do_setlk function in fs/nfs/file.c in the Linux kernel before 2.6.26 allows local users to cause a denial of service (crash) via vectors resulting in an interrupted RPC call that leads to a stray FL_POSIX lock, related to improper handling of a race between fcntl and close in the EINTR case.

Security readout for executives and security teams

CVE-2008-4307 is an old Linux kernel flaw that can let a local user crash a system. It affects kernel behavior around NFS file locking before Linux 2.6.26. The business risk is service disruption on legacy systems, especially shared servers where untrusted local users can run code. Exposure is most plausible on legacy Linux systems running kernels before 2.6.26 or vendor kernels without the relevant backport. Risk is higher where local users, shell accounts, workloads, or tenants can interact with NFS-backed filesystems. Treat this as a legacy-system availability risk. It should not outrank actively exploited internet-facing flaws, but any affected shared or business-critical Linux host should be patched or retired promptly. Mitigation focus: Upgrade kernels older than 2.6.26 to vendor-fixed supported releases.; Apply relevant Red Hat, Debian, Ubuntu, or VMware security updates where applicable.; Restrict local shell access on potentially affected shared systems until remediated..
