CWE-416  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 4.14 or higher.

Overview

Affected versions of this package are vulnerable to Use After Free. 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.
