CVE-2024-6640 pf incorrectly matches different ICMPv6 states in the state table

In ICMPv6 Neighbor Discovery ND, the ID is always 0. When pf is configured to allow ND and block incoming Echo Requests, a crafted Echo Request packet after a Neighbor Solicitation NS can trigger an Echo Reply. The packet has to come from the same host as the NS and have a zero as identifier to...

CVE-2022-35926 Out-of-bounds read in IPv6 neighbor solicitation in Contiki-NG

Contiki-NG is an open-source, cross-platform operating system for IoT devices. Because of insufficient validation of IPv6 neighbor discovery options in Contiki-NG, attackers can send neighbor solicitation packets that trigger an out-of-bounds read. The problem exists in the module...
