CVE-2017-15115 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. The sctp_do_peeloff function in net/sctp/socket.c in the Linux kernel before 4.14 does not check whether the intended netns is used in a peel-off action, which allows local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via crafted system calls.. EPSS estimates a 0.47% chance of exploitation in the next 30 days.
