firewire security

The firewire security tag on WindowsForum covers discussions about security vulnerabilities and issues related to FireWire (IEEE 1394) interfaces, particularly in the context of Linux kernel networking. Recent content highlights CVE-2026-45844, a flaw in the Linux arptables component that mishandles IPv4-over-IEEE1394 ARP packets, leading to incorrect firewall rule matching and potential packet mangling on FireWire network interfaces. While the practical impact is narrow, the tag explores how such obscure kernel edge cases expose brittleness in network filtering when old assumptions outlast the hardware. The tag is relevant for users interested in FireWire security, kernel vulnerabilities, and network filtering edge cases.
