CVE-2026-74597 ip6_tunnel: clear skb2->cb[] in ip6ip6_err()

In the Linux kernel, the following vulnerability has been resolved: ip6tunnel: clear skb2-cb in ip6ip6err ip6ip6err clones an outer IPv6 ICMP error skb, pulls it to the quoted inner IPv6 packet, and then passes the clone to icmpv6send. The clone still carries the outer packet's inet6skbparm in...

CVE-2026-74597

This vulnerability affects the Linux kernel 's ip6_tunnel module, specifically the ip6ip6_err() function. When processing an outer IPv6 ICMP error packet, the function clones and pulls the skb to the quoted inner IPv6 packet but fails to clear skb2->cb[], leaving the outer packet's inet6_skb_p...
