## Overview

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

pinctrl: devicetree: fix refcount leak in pinctrl_dt_to_map()

If we fail to allocate propname buffer, we need to drop the reference
count we just took. Because the pinctrl_dt_free_maps() includes the
droping operation, here we call it directly.

## Affected

- `linux_kernel >= 4.9.334, < 4.10`
- `linux_kernel >= 4.14.300, < 4.15`
- `linux_kernel >= 4.19.267, < 4.19.314`
- `linux_kernel >= 5.4.225, < 5.4.276`
- `linux_kernel >= 5.10.156, < 5.10.217`
- `linux_kernel >= 5.15.80, < 5.15.159`
- `linux_kernel >= 6.0.10, < 6.1.91`
- `linux_kernel >= 6.2, < 6.6.31`
- `linux_kernel >= 6.7, < 6.8.10`
- `linux_kernel = 6.9`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.8.10`
