Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.11.1

Description The issue is related to the implementation of IPv6 packet fragmentation in the Linux kernel, which does not properly handle an invalid option associated with the nexthdr field. This can be exploited by a local attacker to cause a denial of service, potentially leading to an out-of-bounds read or other unspecified impacts, by using crafted socket and send system calls.

Recommendations For Linux kernel versions prior to 4.11.1, update to version 4.11.1 or later to resolve the issue.
