Answer in brief
CVE-2026-14607 records a Medium severity (CVSS 5.5) vulnerability in RT-Thread lwp_syscall.c sys_getaddrinfo memory corruption. The current sources do not mark it as known exploited. The current feed maps n/a/RT-Thread (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 5.5. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

A weakness has been identified in RT-Thread up to 5.0.2. This affects the function sys_getaddrinfo of the file components/lwp/lwp_syscall.c. Executing a manipulation of the argument ai_addr can lead to memory corruption. The attack can only be executed locally. The exploit has been made available to the public and could be used for attacks. The pull request to fix this issue awaits acceptance.
