This vulnerability stems from improper error handling during the initialization of the Multi-Band Headset Controller (MBHC). A local attacker with low privileges could exploit this by triggering a specific sequence of events, leading to an incorrect pointer dereference. This might result in a Denial of Service (DoS), corruption of system memory, or the disclosure of sensitive information." ],
