CVE-2026-10636: use-after-free in zephyrproject zephyrCVE-2026-10636
0

A use-after-free vulnerability exists in Zephyr's IPv4 IGMP implementation in versions 2.6.0 through before 4.5.0. The flaw occurs when the igmp_send() function accesses a network interface pointer after the associated packet memory has been freed, potentially causing undefined behavior or denial of service. The vulnerability can be triggered without authentication via inbound IPv4 IGMP membership queries or local multicast operations. The issue was introduced with IGMPv2 support and fixed by caching the interface pointer before sending. The analogous IPv6 MLD path remains unfixed.
