  "message": "blockdev: check dinfo ptr before using\n\nIf a user decides to punish a guest by revoking its block device via\ndrive_del, and subsequently also attempts to remove the pci device\nbacking it, and the device is using blockdev_auto_del() then we get a\nsegfault when we attempt to access dinfo-\u003eauto_del.[1]\n\nThe fix is to check if drive_get_by_blockdev() actually returns a valid\ndinfo pointer or not.\n\n1.
