A vulnerability, which was classified as critical, was found in FreeBSD up to 11.2/11.3/12.0 (Operating System). Affected is an unknown functionality of the component ICMPv6 Handler. The manipulation as part of a Packet leads to a out-of-bounds write vulnerability. CWE is classifying the issue as CWE-787. The product writes data past the end, or before the beginning, of the intended buffer. This is going to have an impact on availability. CVE summarizes:

In FreeBSD 12.0-STABLE before r350648, 12.0-RELEASE before 12.0-RELEASE-p9, 11.3-STABLE before r350650, 11.3-RELEASE before 11.3-RELEASE-p2, and 11.2-RELEASE before 11.2-RELEASE-p13, the ICMPv6 input path incorrectly handles cases where an MLDv2 listener query packet is internally fragmented across multiple mbufs. A remote attacker may be able to cause an out-of-bounds read or write that may cause the kernel to attempt to access an unmapped page and subsequently panic.

The weakness was shared 08/30/2019 (Website). The advisory is available at security.FreeBSD.org. This vulnerability is traded as CVE-2019-5608 since 01/07/2019.
