In the Linux kernel, the following vulnerability has been resolved:

ipv6: reject malicious packets in ipv6_gso_segment()

syzbot was able to craft a packet with very long IPv6 extension headers leading to an overflow of skb->transport_header.

This 16bit field has a limited range.

Add skb_reset_transport_header_careful() helper and use it from ipv6_gso_segment()
