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

ipvs: fix more places with wrong ipv6 transport offsets

Sashiko reports for more incorrect IPv6 transport offsets.

The app code for TCP was assuming IPv4 network header

even after the ipvsh argument was provided. This can

cause problems with apps over IPv6. As for the only

official app in the kernel tree (FTP) this problem is

harmless because we use Netfilter to mangle the FTP

ports and we do not adjust the TCP seq numbers.

Also, provide correct offset of the ICMPV6 header in

ip_vs_out_icmp_v6() for correct checksum checks when

the IPv6 packet has extension headers. (NVD)
