setsockopt(2) IPv6 sockets input validation error


From the FreeBSD Security Advisory:

A programming error in the handling of some IPv6 socket options within the setsockopt(2) system call may result in memory locations being accessed without proper validation.

It may be possible for a local attacker to read portions of kernel memory, resulting in disclosure of sensitive information. A local attacker can cause a system panic.
