The revision details in the table below reference the git repository information, which was correct at the time of the original WiFi patch. For general information regarding FreeBSD Errata Notices and Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit . I. Background FreeBSD's net80211 kernel subsystem provides infrastructure and drivers for IEEE 802.11 wireless (Wi-Fi) communications. II. Problem Description FreeBSD-SA-22:02.wifi included a number of improvements to net80211 data validation. Some of these changes were not included in the patch provided for FreeBSD 13.0 and via freebsd-update. The changes were included in the git repository. III. Impact The interface affected by the missing change is only available to the superuser. The superuser may be able to cause kernel crash. IV. Workaround No workaround is available. V. Solution Upgrade your system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date, and reboot. Perform one of the following: 1) To update your system via a binary patch: Systems running a RELEASE version of FreeBSD on the amd64, i386, or (on FreeBSD 13 and later) arm64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install # shutdown -r +5min "Installing errata update" 2) 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. # fetch https://security.FreeBSD.org/patches/EN-22:18/wifi.patch # fetch https://security.FreeBSD.org/patches/EN-22:18/wifi.patch.asc # gpg --verify wifi.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 and reboot the system. VI. Correction details This issue is corrected by the corresponding Git commit hash or Subversion revision number in the following stable and release branches: Branch/path Hash Revision - ------------------------------------------------------------------------- releng/13.0/ 0d1db5c3257e releng/13.0-n244782 - ------------------------------------------------------------------------- Run the following command to see which files were modified by a particular commit: # git show --stat Or visit the following URL, replacing NNNNNN with the hash: To determine the commit count in a working tree (for comparison against nNNNNNN in the table above), run: # git rev-list --count --first-parent HEAD VII.
