## Overview

A use-after-free flaw was found in btsdio_remove in drivers\bluetooth\btsdio.c in the Linux Kernel. A call to btsdio_remove with an unfinished job may cause a race problem which leads to a UAF on hdev devices.

## Affected

- `linux_kernel >= 2.6.24, < 4.14.312`
- `linux_kernel >= 4.15, < 4.19.280`
- `linux_kernel >= 4.20, < 5.4.240`
- `linux_kernel >= 5.5, < 5.10.177`
- `linux_kernel >= 5.11, < 5.15.105`
- `linux_kernel >= 5.16, < 6.1.22`
- `linux_kernel >= 6.2, < 6.2.9`
- `h300s`
- `h410c`
- `h410s`
- `h500s`
- `h700s`
- `debian_linux = 10.0`
- `debian_linux = 12.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.2.9`
