CVE request: Linux kernel: net: ipvs stack buffer overflow

   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.

Upstream fix:
-------------
 -> https://git.kernel.org/linus/04bcef2a83f40c6db24222b27a52892cba39dffb
