Subject: CVE request Linux kernel: net: guard tcp_set_keepalive against
 crash

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

    Hello,

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.

Upstream fix:
- -------------
   -> https://git.kernel.org/linus/3e10986d1d698140747fcfc2761ec9cb64c1d582

Reference:

Thank you.
