Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.9

Description The issue is related to the netfilter subsystem in the Linux kernel, which mishandles IPv6 reassembly. This can be exploited by local users via a crafted application that makes socket, connect, and writev system calls, potentially leading to a denial of service (integer overflow, out-of-bounds write, and GPF) or other unspecified impacts.

Recommendations For Linux kernel versions prior to 4.9, update to version 4.9 or later to resolve the issue.
