The Debian security team deemed this advisory irrelevant for Debian:unstable.

Note: Versions mentioned in the description apply only to the upstream kfreebsd-10 package and not the kfreebsd-10 package as distributed by Debian.

In FreeBSD 13.0-STABLE before n245117, 12.2-STABLE before r369551, 11.4-STABLE before r369559, 13.0-RC5 before p1, 12.2-RELEASE before p6, and 11.4-RELEASE before p9, copy-on-write logic failed to invalidate shared memory page mappings between multiple processes allowing an unprivileged process to maintain a mapping after it is freed, allowing the process to read private data belonging to other processes or the kernel.
