UBUNTU-CVE-2026-98111: Medium severity ubuntu/linux-hwe-edge vulnerability

Published Sep 25, 2026
·
Updated

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintel: validate version TLV value lengths btintelparseversiontlv() 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 getunalignedle16(), getunalignedle32(), 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.
