En el kernel de Linux se ha resuelto la siguiente vulnerabilidad:
Bluetooth: bnep: corregir lecturas fuera de límites en tramas RX/TX cortas y en el paso de control a la ruta de Ethernet
Corrige múltiples lecturas fuera de límites en el procesamiento de tramas BNEP de Bluetooth:
1. En bnep_rx_frame() y bnep_ctrl_frame() (net/bluetooth/bnep/core.c), usa pskb_may_pull() para verificar que existen la cabecera BNEP, el byte de tipo de control, el recuento de filtros y las cabeceras de extensión antes de leerlos, y devuelve 0 tras procesar BNEP_CONTROL en lugar de continuar hacia el envío de la trama Ethernet cuando no siguen cabeceras de extensión. 2. En bnep_net_xmit() (net/bluetooth/bnep/netdev.c), verifica con pskb_may_pull() que skb->len >= ETH_HLEN antes de leer la cabecera Ethernet de 14 bytes, para evitar una lectura de heap fuera de límites y una fuga de información (infoleak) en tramas TX AF_PACKET cortas.
