CVE-2026-80793

This Linux kernel vulnerability affects the IPv4 fragmentation path in ip_do_fragment() . When the effective MTU is smaller than the IPv4 header length plus 8, the function passes a zero-length payload to ip_frag_next() , causing the fragmentation state to stall indefinitely. The result is a soft...
