CVE-2026-45816

NULL Pointer Dereference vulnerability in Apache NimBLE in LE Long Term Key Request event. This requires disabled asserts (otherwise assert would trigger before NULL dereference) and bogus (or misbehaving) controller, thus severity is low. This issue affects Apache NimBLE: through 1.9.0. Users are recommended to upgrade to version 1.10.0, which fixes the issue.

Summary		(es) Vulnerabilidad de desreferencia de puntero NULL en Apache NimBLE en el evento de Solicitud de Clave a Largo Plazo LE. Esto requiere aserciones deshabilitadas (de lo contrario, la aserción se activaría antes de la desreferencia de NULL) y un controlador defectuoso (o con mal funcionamiento), por lo tanto, la gravedad es baja. Este problema afecta a Apache NimBLE: hasta la versión 1.9.0. Se recomienda a los usuarios actualizar a la versión 1.10.0, que corrige el problema.
