It turns out that syzkaller can\ntrigger the retransmit after fallback and before processing any other\nincoming packet - so that snd_una is still left uninitialized.\n\nAddress the issue explicitly initializing snd_una together with snd_nxt\nand write_seq."

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mptcp: aseg\u00farese de que snd_una se inicialice correctamente al conectarse. Esto est\u00e1 estrictamente relacionado con el commit fb7a0d334894 (\"mptcp: aseg\u00farese de que snd_nxt se inicialice correctamente al conectarse\"). Resulta que syzkaller puede activar la retransmisi\u00f3n despu\u00e9s del respaldo y antes de procesar cualquier otro paquete entrante, de modo que snd_una a\u00fan permanece sin inicializar. Solucione el problema al inicializar expl\u00edcitamente snd_una junto con snd_nxt y write_seq."
