CVE-2026-13351 net: Maliciously fragmented IPv6 packets can prevent receiving/processing future incoming packets
Zephyr's IPv6 network stack can be prevented from receiving or processing future incoming packets by sending a small number of maliciously fragmented IPv6 packets. When such a packet is handled by the fragment-header processing path, the associated RX network packet buffer allocated from a memory...
CVE-2026-10636
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...
CVE-2025-12899
A flaw in Zephyr’s network stack allows an IPv4 packet containing ICMP type 128 to be misclassified as an ICMPv6 Echo Request. This results in an out-of-bounds memory read and creates a potential information-leak vulnerability in the networking subsystem...
