Race condition in OpenBSD VFS allows local users to cause a denial of service (kernel panic) by (1) creating a pipe in one thread and causing another thread to set one of the file descriptors to NULL via a close, or (2) calling dup2 on a file descriptor in one process, then setting the descriptor to NULL via a close in another process that is created via rfork.

Security readout for executives and security teams

CVE-2001-1047 is a local denial-of-service issue in OpenBSD VFS. A user already able to run code on the system could trigger a race condition that causes a kernel panic. The business impact is service interruption on affected OpenBSD hosts, not data theft or remote compromise based on the provided sources. Exposure is most relevant to legacy OpenBSD systems that allow local users, shell access, or local process execution by untrusted parties. The bundle does not identify specific affected versions or products beyond OpenBSD VFS. Treat this as a legacy platform risk. It is not described as remote code execution, but affected multi-user OpenBSD systems could be crashed by a local user. Prioritize if OpenBSD still supports business-critical services or untrusted local accounts. Mitigation focus: Inventory OpenBSD systems, especially legacy or multi-user hosts.; Check OpenBSD vendor guidance and historical errata for the affected release.; Move unsupported OpenBSD systems to a supported vendor-maintained release path..
