This can be exploited toelevate privileges.Remove the JDF_SELECTED micro-optimization. doselwakeup() is a no-op ifno one ever called selrecord() on the file description, so I see noreason to complicate the code to avoid the call.Add some regression tests.Approved by: soSecurity: FreeBSD-SA-26:19.fileSecurity: CVE-2026-45251Fixes: 66d8ffe3046d ("jaildesc: add kevent support")Reviewed by: kib, jamieDifferential Revision: https://reviews.freebsd.org/D56945 List of files: /freebsd/tests/sys/kern/jaildesc.c Sun, 10 May 2026 17:15:45 +0200 Mark Johnston <markj@FreeBSD.org>
