CVE-2017-9242  (opens in a new tab)
CWE-20  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 4.11.4 or higher.

Overview

Affected versions of this package are vulnerable to Improper Input Validation. The __ip6_append_data function in net/ipv6/ip6_output.c in the Linux kernel through 4.11.3 is too late in checking whether an overwrite of an skb data structure may occur, which allows local users to cause a denial of service (system crash) via crafted system calls.
