## Overview

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

Bluetooth: btintel: Fix null ptr deref in btintel_read_version

If hci_cmd_sync_complete() is triggered and skb is NULL, then
hdev->req_skb is NULL, which will cause this issue.

## Affected

- `linux_kernel < 4.19.312`
- `linux_kernel >= 4.20, < 5.4.274`
- `linux_kernel >= 5.5, < 5.10.215`
- `linux_kernel >= 5.11, < 5.15.155`
- `linux_kernel >= 5.16, < 6.1.86`
- `linux_kernel >= 6.2, < 6.6.27`
- `linux_kernel >= 6.7, < 6.8.6`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.8.6`
