## Overview

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

PM / devfreq: Fix buffer overflow in trans_stat_show

Fix buffer overflow in trans_stat_show().

Convert simple snprintf to the more secure scnprintf with size of
PAGE_SIZE.

Add condition checking if we are exceeding PAGE_SIZE and exit early from
loop. Also add at the end a warning that we exceeded PAGE_SIZE and that
stats is disabled.

Return -EFBIG in the case where we don't have enough space to write the
full transition table.

Also document in the ABI that this function can return -EFBIG error.

## Affected

- `linux_kernel >= 3.8, < 5.10.216`
- `linux_kernel >= 5.11, < 5.15.149`
- `linux_kernel >= 5.16, < 6.1.76`
- `linux_kernel >= 6.2, < 6.6.15`
- `linux_kernel >= 6.7, < 6.7.3`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.7.3`
