## Overview

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

Bluetooth: btintel: validate version TLV value lengths

btintel_parse_version_tlv() verifies that a complete TLV is present in
the response, but it does not ensure that the value is long enough for
the specific TLV type. A short value can therefore cause an
out-of-bounds read through get_unaligned_le16(), get_unaligned_le32(),
or memcpy().

Reject values shorter than the minimum required by each known TLV type.
Also reject responses that do not contain the Command Complete Status
field.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
