kernel: net: ipv6: fix NOREF dst use in seg6 and rpl lwtunnels

A flaw was found in the Linux kernel's IPv6 networking implementation, specifically within the seg6 and rpl lwtunnels. A race condition can occur when handling destination cache entries, where a NOREF no reference destination object is used after it has been freed. This use-after-free vulnerabili...
