CVE-2007-4567

35
FAUCET Score

CVE-2007-4567 describes a denial-of-service vulnerability in the Linux kernel before version 2.6.22, specifically within the ipv6_hop_jumbo function, affecting systems processing IPv6 traffic. This critical vulnerability (CVSS 7.8) allows remote, unauthenticated attackers to trigger a kernel panic and system crash through a crafted IPv6 packet, due to improper validation of the hop-by-hop IPv6 extended header. While not actively exploited in the wild, an ExploitDB entry exists (EDB-30902), indicating public exploit code availability. Despite its age and high FAUCET Risk Score, there is no evidence of active exploitation, Metasploit/Nuclei modules, or significant community discussion or media coverage.
