Description
In 11.4-PRERELEASE before r360733 and 11.3-RELEASE before p13, improper mbuf handling in the kernel causes a use-after-free bug by sending IPv6 Hop-by-Hop options over the loopback interface. The use-after-free situation may result in unintended kernel behaviour including a kernel panic.
