CVE-2010-4165 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.35% chance of exploitation in the next 30 days.
