CVE-2026-10639: use-after-free in zephyrproject zephyrCVE-2026-10639 0 CVE-2026-10639 is a use-after-free vulnerability in the Zephyr project's native IPv4 stack affecting versions from 1.14.0 through 4.4.0. The flaw occurs in the handling of ICMPv4 echo requests, where a packet is freed before its interface pointer is accessed for statistics updates, leading to a use-after-free read and potential write through a stale pointer. This can cause corrupted interface statistics or a remotely triggerable denial of service (DoS). The vulnerability is exploitable by any remote host sending ICMP echo requests (pings) and requires the CONFIG_NET_STATISTICS_ICMP configuration. The defect was introduced in 2019 and fixed by caching the interface pointer before sending the packet. The CVSS score is 4.8 (medium severity).
