## Overview

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

hwmon: (coretemp) Fix out-of-bounds memory access

Fix a bug that pdata->cpu_map[] is set before out-of-bounds check.
The problem might be triggered on systems with more than 128 cores per
package.

## Affected

- `linux_kernel >= 4.19.264, < 4.19.307`
- `linux_kernel >= 5.4.221, < 5.4.269`
- `linux_kernel >= 5.10.152, < 5.10.210`
- `linux_kernel >= 6.1, < 6.1.78`
- `linux_kernel >= 6.2, < 6.6.17`
- `linux_kernel >= 6.7, < 6.7.5`
- `linux_kernel = 6.8`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.7.5`
