CVE-2026-80793 ipv4: reject undersized MTUs in ip_do_fragment()
In the Linux kernel, the following vulnerability has been resolved: ipv4: reject undersized MTUs in ipdofragment ipdofragment subtracts the IPv4 header length from the effective MTU and passes the resulting payload MTU to ipfragnext. If the effective MTU is smaller than hlen + 8, ipfragnext round...
