CyberRota Analysis
AI-GeneratedThe vulnerability in the Linux kernel affects the IP Virtual Server (IPVS) component, where incorrect IPv6 transport offsets can lead to improper handling of IPv6 packets by applications, particularly those relying on TCP. While the primary impact is mitigated for the official FTP application due to Netfilter adjustments, other applications using IPv6 may experience issues. Organizations utilizing Linux systems with IPVS should prioritize this fix to ensure robust IPv6 packet processing and maintain application reliability.
Original NVD Description
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.
