Summary

The Bluetooth driver in MediaTek products is affected by a vulnerability that allows unauthorized read and write access to registers due to inadequate access control measures. This flaw could potentially lead to the local disclosure of sensitive information, necessitating system execution privileges for exploitation. Importantly, user interaction is not required for an attacker to exploit this vulnerability, which increases its risk profile. A patch has been issued to address this issue. For further details, consult the product security bulletin from MediaTek.
