Description Prasad J Pandit 2014-09-15 07:28:36 EDT 
Linux kernel built with the Networking support(CONFIG_NET) is vulnerable to a
crash, while resetting a socket timer. It could occur while doing a
setsockopt(SO_KEEPALIVE) call.

A privileged user/process able to create RAW socket could use this flaw to
crash the system kernel resulting in DoS.

Linux 5 and 6 may address this issue.
