Hello,

Linux kernel built with the IP Virtual Server(CONFIG_IP_VS) support
is vulnerable to a buffer overflow flaw. It could occur while
setting or retrieving socket options via setsockopt(2) or
getsockopt(2) calls. Though a user needs to have CAP_NET_ADMIN
privileges to perform these IP_VS operations.

A user/program with CAP_NET_ADMIN privileges could use this flaw
to further escalate their privileges on a system.
