Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.10
Description
An issue in the Linux kernel's netfilter component can cause a use-after-free in the packet processing context due to mishandled per-CPU sequence counts during concurrent iptables rules replacement. This could be exploited with the CAP NET ADMIN capability in an unprivileged namespace, potentially affecting the confidentiality, integrity, and availability of protected information.
Recommendations
For Linux kernel versions prior to 5.10, update to a version 5.10 or later to resolve the issue.
At the moment, there is no information about additional mitigation measures for this vulnerability.
