Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.6

Description The issue allows local users to cause a denial of service or possibly obtain sensitive information from kernel heap memory by providing a crafted offset value. This is achieved by leveraging in-container root access, which leads to crossing a ruleset blob boundary in the netfilter subsystem.

Recommendations For Linux kernel versions prior to 4.6, update to version 4.6 or later to resolve the issue. As a temporary workaround, consider restricting in-container root access to minimize the risk of exploitation.
