A vulnerability in the Linux kernel's IPv4 raw socket implementation allowed malformed IP packets with an Internet Header Length (IHL) field less than 5 to bypass validation. This flaw could lead to out-of-bounds memory access and cause a kernel panic. The issue has been resolved in updated Linux kernel versions.
