CVE-2026-10639 Use-after-free reading `net_pkt_iface()` of a sent ICMPv4 echo-reply packet in `icmpv4_handle_echo_request()`

In Zephyr's native IPv4 stack, icmpv4handleechorequest in subsys/net/ip/icmpv4.c builds an echo-reply packet reply, hands it to nettrysenddata, and then, on success, calls netstatsupdateicmpsentnetpktifacereply. nettrysenddata transfers ownership of reply to the TX path netiftryqueuetx - netiftx ...

CVE-2026-10639

Summary: Zephyr’s native IPv4 icmpv4_handle_echo_request() can perform a use-after-free when updating per-interface statistics after sending an ICMP echo reply. The code hands the echo-reply to the TX path, which may drop the packet and free the net_pkt before the post-send stats update runs. As ...

CVE-2026-10637 Use-after-free of `net_pkt` in IPv6 MLD send path triggerable by a link-local MLD Query

subsys/net/ip/ipv6mld.c:mldsend read the packet interface via netpktifacepkt after netsenddatapkt returned successfully. Per the network stack's ownership contract include/zephyr/net/netcore.h, and the explicit warning in subsys/net/ip/netcore.c:453-460 'do not use pkt after that call', a...

CVE-2026-10637

CVE-2026-10637 describes a use-after-free in Zephyr’s IPv6 MLD path: after net_send_data(pkt) returns, the code reads net_pkt_iface(pkt) from a freed net_pkt, risking NULL or stale pointers and potential crash or memory corruption. The root cause is violating the network stack ownership contract;...

CVE-2026-10636 Use-after-free in Zephyr IPv4 IGMP send path (`igmp_send`)

In Zephyr's IPv4 IGMP implementation, igmpsend in subsys/net/ip/igmp.c read the network interface back out of the packet via netpktifacepkt after the packet had been handed to netsenddata. On the successful-send path the packet's last reference may already have been released by the L2 driver or b...
