## Overview

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

iio: light: bh1780: fix PM runtime leak on error path

Move pm_runtime_put_autosuspend() before the error check to ensure
the PM runtime reference count is always decremented after
pm_runtime_get_sync(), regardless of whether the read operation
succeeds or fails.

## Affected

- `linux_kernel >= 4.7, < 5.10.253`
- `linux_kernel >= 5.11, < 6.1.167`
- `linux_kernel >= 6.2, < 6.6.130`
- `linux_kernel >= 6.7, < 6.18.19`
- `linux_kernel >= 6.19, < 6.19.9`
- `linux_kernel = 7.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.19.9`
