Memory corruption via Alternative Frequency offset overflow

Buffer overflow in Qualcomm FM Host firmware allows local users to corrupt memory by setting an Alternative Frequency offset to 255. Qualcomm maps the flaw to CWE-120 but does not disclose the affected function, destination buffer, or exact unchecked copy operation. Local low-privileged access and affected embedded FM hardware are required; the documented result is FM Host memory corruption, while further behavior remains undisclosed.
