## Overview

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

platform/x86: dell-wmi-sysman: Fix WMI data block retrieval in sysfs callbacks

After retrieving WMI data blocks in sysfs callbacks, check for the
validity of them before dereferencing their content.

## Affected

- `linux_kernel >= 5.11, < 5.15.187`
- `linux_kernel >= 5.16, < 6.1.144`
- `linux_kernel >= 6.2, < 6.6.97`
- `linux_kernel >= 6.7, < 6.12.37`
- `linux_kernel >= 6.13, < 6.15.6`
- `linux_kernel = 6.16`
- `debian_linux = 11.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.15.6`
