## Overview

In the Linux kernel, the following vulnerability has been resolved:

spi: fix resource leaks on device setup failure

Make sure to call controller cleanup() if spi_setup() fails while
registering a device to avoid leaking any resources allocated by
setup().

## Affected

- `linux_kernel >= 5.4.126, < 5.5`
- `linux_kernel >= 5.10.44, < 5.11`
- `linux_kernel >= 5.12.11, < 5.13`
- `linux_kernel >= 5.13.1, < 6.1.176`
- `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 = 5.13`

## Remediation

Upgrade past the affected range:

- `linux_kernel 7.0.4`
