CVE-2026-10646: use-after-free in zephyrproject zephyrCVE-2026-10646
0

A use-after-free vulnerability exists in Zephyr's BSD-sockets getaddrinfo() implementation due to improper handling of asynchronous DNS resolver queries. This flaw allows a stale callback to access a stack-allocated state object after it has gone out of scope, potentially leading to memory corruption or denial of service. The vulnerability affects Zephyr versions 4.0.0 through 4.4.0. The issue arises when a DNS query times out and is retried without cancelling the previous query, enabling an attacker to influence the stale callback via spoofed or replayed network responses.
