The do_tcp_setsockopt function in net/ipv4/tcp.c in the Linux kernel
before 2.6.37-rc2 does not properly restrict TCP_MAXSEG (aka MSS)
values, which allows local users to cause a denial of service (OOPS)
via a setsockopt call that specifies a small value, leading to a
divide-by-zero error or incorrect use of a signed integer.
