CVE-2007-4567

Publication date 21 December 2007

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
