Description

Mathias Krause discovered a bounds checking error for netlink messages requesting SOCK_DIAG_BY_FAMILY. An unprivileged local user could exploit this flaw to crash the system or run programs as an administrator.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
