A flaw was found in the Linux kernel's ip6_vti component, which handles IPv6 Virtual Tunnel Interfaces. A local attacker with certain network administration privileges in one isolated network environment (network namespace) could exploit this vulnerability. This allows them to modify the configuration of a tunnel in a different isolated network environment where they do not have full administrative rights, potentially leading to unauthorized network changes or the redirection of network traffic.
