CVE-2026-110912

In DragonFly BSD through 6.4.2 before 4bb22ff, the ARP input handlers arpintr and inarpinput sys/netinet/ifether.c do not validate the hardware address length arhln and protocol address length arpln fields of incoming ARP packets. inarpreply then uses these attacker-controlled values as memcpy...

CVE-2026-110912

In DragonFly BSD (through 6.4.2 before 4bb22ff), the ARP input handlers arpintr() and in_arpinput() in sys/netinet/if_ether.c fail to validate the ar_hln and ar_pln fields of incoming ARP packets. Consequently, in_arpreply() uses these attacker-controlled values as memcpy lengths when copying fro...
