La vulnerabilidad tiene un nivel cr\u00edtico de peligrosidad (9.8 de 10) ya que puede llevar a la ejecuci\u00f3n remota de c\u00f3digo al procesar paquetes Bluetooth espec\u00edficamente dise\u00f1ados.    <\/p>\n<p>Google a\u00fan no ha revelado una descripci\u00f3n detallada de la vulnerabilidad, pero investigadores independientes afirman que el problema no afecta a tel\u00e9fonos inteligentes comunes y solo se refiere a dispositivos Bluetooth que pueden actuar como altavoces, como altavoces inteligentes, relojes inteligentes y sistemas de informaci\u00f3n y entretenimiento en autom\u00f3viles. Para explotar la vulnerabilidad, el usuario debe emparejar su dispositivo con el dispositivo del atacante, es decir, para bloquear el problema de manera indirecta, basta con no aceptar solicitudes de emparejamiento sospechosas (en el bolet\u00edn de Google se menciona que para la explotaci\u00f3n no se requieren acciones por parte del usuario).    <\/p>\n<p>La correcci\u00f3n consiste en agregar una llamada para verificar la existencia de la Base de Datos de Descubrimiento al trabajar con el perfil Bluetooth de Manos Libres y detener la b\u00fasqueda de pares utilizando el protocolo SDP (Protocolo de Descubrimiento de Servicios), as\u00ed como reiniciar y limpiar la estructura p_disc_db (\u00abbase de datos de descubrimiento\u00bb). Se realizan ciertas manipulaciones para devolver errores y reanudar conexiones durante el proceso de identificaci\u00f3n del servicio Bluetooth y la negociaci\u00f3n de la interacci\u00f3n. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/es\/server\/dts-los-angeles\/\"   title=\"servidores\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3990\">servidores<\/a> el cliente lleva a una referencia a un \u00e1rea de memoria ya liberada (use-after-free).     <\/p>\n<p>La soluci\u00f3n ya se ha integrado en la base de c\u00f3digo de LineageOS. Un prototipo temprano de exploit est\u00e1 disponible, causando un cierre inesperado al iniciar Android en un emulador especial. Tambi\u00e9n se han visto intentos de venta de un exploit funcional en la red, pero aparentemente son intentos de distribuci\u00f3n de malware o intentos de estafa por parte de criminales.                    <\/p>\n<p>Adem\u00e1s de esta vulnerabilidad, la actualizaci\u00f3n de Android de noviembre incluye una correcci\u00f3n de la vulnerabilidad CVE-2025-48581, que conduce a un aumento de privilegios. El problema solo afecta a Android 16 y est\u00e1 marcado como cr\u00edtico. La causa de la vulnerabilidad es un error l\u00f3gico en la funci\u00f3n VerifyNoOverlapInSessions del archivo apexd.cpp, que permite bloquear la instalaci\u00f3n de actualizaciones que corrigen problemas de seguridad. Se se\u00f1ala que la vulnerabilidad puede ser utilizada para un aumento de privilegios local. No se requiere que el usuario realice ninguna acci\u00f3n para llevar a cabo el ataque.<br \/>\n<br \/>Fuente: <a content=\"nofollow\" rel=\"nofollow\"
