CVE-2026-10638

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 -...

CVE-2026-10637

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 send path: after net_send_data(pkt) returns, mld_send() reads net_pkt_iface(pkt), which may point to freed memory because ownership transfers to the L2 driver and the packet is returned to the k_mem_slab. If the freed slot has been re...

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...
