Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ip6tunnel: The array skb2-cb was cleared in ip6ip6err. ip6ip6err clones an outer IPv6 ICMP error packet, moves it into the quoted inner IPv6 packet, and then passes the cloned packet to icmpv6send. The cloned packet still carries...
