 For general information regarding FreeBSD Errata Notices and Security
 Advisories, including descriptions of the fields above, security
 branches, and the following sections, please visit
 <URL:https://security.FreeBSD.org/>.
 
 I.   Background
 
 kevent(2) is a system call which provides a generic method of notifying the
 caller when a caller-specified event happens or a condition holds.  One use
 for kevent(2) is to wait for a specified timeout to elapse.
 
 II.  Problem Description
 
 The kevent(2) implementation in the kernel contains a race condition which
 can be triggered when an event is added and fires shortly after.  Most event
 types are not affected, but timer events can trigger the race if the timeout
 duration is very short.
 
 III. Impact
 
 The race condition can cause corruption of a queue structure, leading to
 a kernel panic when it is later accessed.  Applications using kevent(2) may
 trigger the panic if their usage causes the race condition to occur.
 
 IV.  Workaround
 
 No workaround is available.
 
 V.   Solution
 
 Perform one of the following:
 
 1) Upgrade your system to a supported FreeBSD stable or release / security
 branch (releng) dated after the correction date, and reboot.
 
 2) To update your system via a binary patch:
 
 Systems running a RELEASE version of FreeBSD on the i386 or amd64
 platforms can be updated via the freebsd-update(8) utility:
 
 # freebsd-update fetch
 # freebsd-update install
 # shutdown -r +30 "Rebooting for errata update"
 
 3) To update your system via a source code patch:
 
 The following patches have been verified to apply to the applicable
 FreeBSD release branches.
 
 a) Download the relevant patch from the location below, and verify the
 detached PGP signature using your PGP utility.
 
 [FreeBSD 11.2]
 # fetch https://security.FreeBSD.org/patches/EN-19:05/kqueue.patch
 # fetch https://security.FreeBSD.org/patches/EN-19:05/kqueue.patch.asc
 # gpg --verify kqueue.patch.asc
 
 b) Apply the patch.  Execute the following commands as root:
 
 # cd /usr/src
 # patch < /path/to/patch
 
 c) Recompile your kernel as described in
 <URL:https://www.FreeBSD.org/handbook/kernelconfig.html> and reboot the
 system.
 
 VI.  Correction details
 
 The following list contains the correction revision numbers for each
 affected branch.
