CVE-2007-4567
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)…
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 14.3%, higher than 96% of all known CVEs. Patch or mitigate before the next change window.
