CVE-2026-107170: NULL pointer dereference vulnerability

A flaw was found in m17n-lib. A partial failure during library initialization can leave an internal driver pointer uninitialized. Under specific error conditions, such as system resource exhaustion or database corruption, an application attempting to open an input method dereferences this null pointer without proper validation. This issue causes the application to crash, resulting in a Denial of Service (DoS).
