Description

In the Linux kernel, the following vulnerability has been resolved: scsi: sd: fix missing put_disk() when device_add(&disk_dev) fails If device_add(&sdkp->disk_dev) fails, put_device() runs scsi_disk_release(), which frees the scsi_disk but leaves the gendisk referenced. The device_add_disk() error path in sd_probe() calls put_disk(gd); call put_disk(gd) here to mirror that cleanup.
