Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: nfc: corrige la posible deref del puntero NULL en nfc_genl_dump_ses_done La devolución de llamada de netlink done() nfc_genl_dump_ses_done() debe verificar si el argumento recibido no es NULL, porque su asignación podría fallar antes en dumpit() (nfc_genl_dump_ses()).
