Zephyr's IPv6 Neighbor Discovery send paths netipv6sendna, netipv6sendns, netipv6sendrs in subsys/net/ip/ipv6nbr.c updated the per-interface ICMP-sent statistics by calling netpktifacepkt after netsenddatapkt had already returned successfully. On the success path the network stack owns and releas...
CVE-2026-10638 Use-after-free in Zephyr ICMPv6 RX path when updating statistics after sending an echo reply or error
subsys/net/ip/icmpv6.c reads the network interface from a netpkt after that packet has been handed to nettrysenddata. In icmpv6handleechorequest and neticmpv6senderror, the post-send statistics update calls netpktifacereply/netpktifacepkt on the just-sent packet. The send path nettrysenddata -...

Zephyr's native TCP stack iterates the global connection list in nettcpforeach subsys/net/ip/tcp.c using the SYSSLISTFOREACHCONTAINERSAFE macro, which caches a pointer to the next list node. Prior to this fix the function released tcplock while invoking the per-connection callback and re-acquired...
