CVE-2026-98460
En el kernel de Linux se ha resuelto la siguiente vulnerabilidad:
Bluetooth: hci_sock: rechazar los valores OCF fuera de rango
El filtro de seguridad del socket HCI sin procesar dispone de 128 bits OCF por cada OGF soportado, pero enmascara el OCF de 10 bits con 127 antes de buscar el comando. Por tanto, un socket sin privilegios puede enviar un OCF reservado que coincide (alias) con un comando de la lista de permitidos módulo 128.
Un controlador conforme debería rechazar los opcodes reservados. No obstante, la decisión de seguridad debe aplicarse al opcode que se enviará realmente, sobre todo porque el comportamiento específico del controlador queda fuera del control de la pila del host.
Leer descripción completaMostrar menos
Rechazar los valores OCF que el filtro de seguridad no puede representar, en lugar de asignarlos a un comando no relacionado.
