7.8
HIGH · CVSS 2.0 · EPSS 14.3% (pctl 97)
Patch early
A public exploit exists.
Description
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.
