The kqueue mechanism in FreeBSD 4.3 through 4.6 STABLE allows local users to cause a denial of service (kernel panic) via a pipe call in which one end is terminated and an EVFILT_WRITE filter is registered for the other end.

Security readout for executives and security teams

This is an old FreeBSD local denial-of-service flaw. A user with local access could trigger a kernel panic through the kqueue mechanism, taking the system down. It is not described as remote code execution or data theft in the provided sources. Exposure is most likely limited to legacy FreeBSD 4.3 through 4.6 STABLE systems where untrusted or low-privileged local users can run code. Modern systems are not identified as affected in the provided bundle. Treat this as a legacy platform availability risk. It is not flagged as actively exploited, but any still-running affected FreeBSD host with local users could be crashed and should be remediated or isolated. Mitigation focus: Inventory for FreeBSD 4.3 through 4.6 STABLE hosts.; Review FreeBSD-SA-02:37.kqueue for vendor remediation guidance.; Upgrade or retire affected legacy FreeBSD systems where feasible..
