## Overview

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

Bluetooth: Ignore too large handle values in BIG

hci_le_big_sync_established_evt is necessary to filter out cases where the
handle value is belonging to ida id range, otherwise ida will be erroneously
released in hci_conn_cleanup.

## Affected

- `linux_kernel >= 6.5.12, < 6.6`
- `linux_kernel >= 6.6.2, < 6.6.39`
- `linux_kernel >= 6.7, < 6.9.9`
- `linux_kernel = 6.10`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.9.9`
