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 The vmci(4) driver implements VMware Virtual Machine Communication Interface for FreeBSD. It allows virtual machines to communicate with host kernel modules and VMware hypervisors. II. Problem Description An error during driver initialization results in a kernel panic due to unallocated resources being freed up. III. Impact The vmci(4) driver is loaded automatically by devd when the system is being run on the VMWare hypervisor. The kernel panic happens at the system boot stage. 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. 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 now 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-21:28/vmci.patch # fetch https://security.FreeBSD.org/patches/EN-21:28/vmci.patch.asc # gpg --verify vmci.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 - ------------------------------------------------------------------------- stable/13/ 4e5c1be4202a stable/13-n247688 releng/13.0/ 847819dca14d releng/13.0-n244763 stable/12/ r370935 releng/12.2/ r370979 - ------------------------------------------------------------------------- For FreeBSD 13 and later: 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 For FreeBSD 12 and earlier: Run the following command to see which files were modified by a particular revision, replacing NNNNNN with the revision number: # svn diff -cNNNNNN --summarize svn://svn.freebsd.org/base Or visit the following URL, replacing NNNNNN with the revision number: VII.
