The virtual memory management system in FreeBSD 4.5-RELEASE and earlier does not properly check the existence of a VM object during page invalidation, which allows local users to cause a denial of service (crash) by calling msync on an unaccessed memory map created with MAP_ANON and MAP_NOSYNC flags.

Security readout for executives and security teams

This is an old FreeBSD kernel denial-of-service issue. A user with local access could crash systems running FreeBSD 4.5-RELEASE or earlier by triggering a virtual memory handling bug. It does not describe remote compromise or data theft, but it can affect availability on legacy systems. Exposure is likely limited to legacy FreeBSD 4.5-RELEASE or earlier systems where untrusted or low-privileged local users can execute code. Modern FreeBSD versions are not identified as affected in the provided sources. Treat this as a legacy-platform availability risk. It is not presented as a remote breach issue, but affected systems can be crashed by local users. Priority should depend on whether business-critical FreeBSD 4.5-era systems still exist. Mitigation focus: Identify any FreeBSD 4.5-RELEASE or earlier systems.; Review FreeBSD-SA-02:22 for vendor-approved corrective action.; Upgrade or retire unsupported FreeBSD installations where feasible..
