CVE-2026-19577
netrouteipv6packet in subsys/net/ip/routeipv6.c resolved the nexthop's link-layer address with netnbrgetlladdrnbr-idx without first checking whether the neighbor cache entry actually had a linked link-layer address. An unresolved neighbor carries idx == NETNBRLLADDRUNKNOWN 0xff, and netnbrgetllad...
CVE-2026-19577
The Zephyr RTOS contains an out-of-bounds read vulnerability in the IPv6 route forwarding logic within subsys/net/ip/route_ipv6.c. The net_route_ipv6_packet() function calls net_nbr_get_lladdr() without verifying if a neighbor cache entry has a linked link-layer address. When a neighbor is unreso...
