Official description

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintel: Validate length before parsing diagnostics TLV btintel_diagnostics() accesses tlv->val[0] without first validating that the diagnostics VSE is long enough to contain that field, so may cause reading data beyond the received frame.
