Detailsinfo

A vulnerability was found in FreeBSD up to 11.2/11.3/12.0 (Operating System). It has been classified as critical. This affects an unknown code of the component IPv6 Stack. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. The summary by CVE is:

In FreeBSD 12.0-STABLE before r350828, 12.0-RELEASE before 12.0-RELEASE-p10, 11.3-STABLE before r350829, 11.3-RELEASE before 11.3-RELEASE-p3, and 11.2-RELEASE before 11.2-RELEASE-p14, a missing check in the function to arrange data in a chain of mbufs could cause data returned not to be contiguous. Extra checks in the IPv6 stack could catch the error condition and trigger a kernel panic, leading to a remote denial of service.

The weakness was disclosed 08/30/2019 as not defined mailinglist post (Bugtraq). The advisory is shared at seclists.org. This vulnerability is uniquely identified as CVE-2019-5611 since 01/07/2019.
