CVE-2026-14607 RT-Thread lwp_syscall.c sys_getaddrinfo memory corruption

A weakness has been identified in RT-Thread up to 5.0.2. This affects the function sysgetaddrinfo of the file components/lwp/lwpsyscall.c. Executing a manipulation of the argument aiaddr can lead to memory corruption. The attack can only be executed locally. The exploit has been made available to...

PT-2026-55581

Name of the Vulnerable Software and Affected Versions RT-Thread versions prior to 5.0.3 Description A memory corruption issue exists in the sys getaddrinfo function within the components/lwp/lwp syscall.c file. A local attacker can trigger this by manipulating the ai addr argument. Recommendation...

CVE-2026-10646

Zephyr's BSD-sockets getaddrinfo implementation subsys/net/lib/sockets/getaddrinfo.c passes a pointer to a stack-allocated state object struct getaddrinfostate aistate as the userdata of an asynchronous DNS resolver query. The socket layer waits on a semaphore with a timeout deliberately set...

CVE-2026-10646 Use-after-return in `zsock_getaddrinfo()` when a timed-out DNS query is retried without cancellation

CVE-2026-10646

Zephyr's BSD-sockets getaddrinfo() (subsys/net/lib/sockets/getaddrinfo.c) has a use-after-return risk from a stack-allocated ai_state being kept as user_data during a DNS resolver retry. If a semaphore wait times out and the code retries without cancelling the previous query or resetting the sema...
