CVE-2026-74532

Bluetooth: btintel: Validate length before parsing diagnostics TLV

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.

Fix by validating the length before access.
