## Overview

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.

## Affected

- `linux_kernel >= 4.4.288, < 4.5`
- `linux_kernel >= 4.9.286, < 4.10`
- `linux_kernel >= 4.14.250, < 4.15`
- `linux_kernel >= 4.19.210, < 4.20`
- `linux_kernel >= 5.4.152, < 5.5`
- `linux_kernel >= 5.10.72, < 5.11`
- `linux_kernel >= 5.14.11, < 5.15`
- `linux_kernel >= 5.15.1, < 6.1.175`
- `linux_kernel >= 6.2, < 6.6.140`
- `linux_kernel >= 6.7, < 6.12.86`
- `linux_kernel >= 6.13, < 6.18.27`
- `linux_kernel >= 6.19, < 7.0.4`
- `linux_kernel = 5.15`

## Remediation

Upgrade past the affected range:

- `linux_kernel 7.0.4`
