CVE-2017-5986 is a vulnerability of currently unknown severity. Race condition in the sctp_wait_for_sndbuf function in net/sctp/socket.c in the Linux kernel before 4.9.11 allows local users to cause a denial of service (assertion failure and panic) via a multithreaded application that peels off an association in a certain buffer-full state.. EPSS estimates a 1.16% chance of exploitation in the next 30 days.
