  - In the Linux kernel, the following vulnerability has been resolved: ata: libata-transport: fix double
    ata_host_put() in ata_tport_add() In the error path in ata_tport_add(), when calling put_device(),
    ata_tport_release() is called, it will put the refcount of 'ap->host'. And then ata_host_put() is called
    again, the refcount is decreased to 0, ata_host_release() is called, all ports are freed and set to null.
    When unbinding the device after failure, ata_host_stop() is called to release the resources, it leads a
    null-ptr-deref(), because all the ports all freed and null. Unable to handle kernel NULL pointer
