Last modified

CVE-2007-4567 is a vulnerability of currently unknown severity. The ipv6_hop_jumbo function in net/ipv6/exthdrs.c in the Linux kernel before 2.6.22 does not properly validate the hop-by-hop IPv6 extended header, which allows remote attackers to cause a denial of service (NULL pointer dereference and kernel panic) via a crafted IPv6 packet.. EPSS estimates a 14.34% chance of exploitation in the next 30 days.
