Vulnerability from variot
In Bluetooth, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS06784351; Issue ID: ALPS06784351. MediaTek Inc. is the world's fourth largest fab semiconductor company, with a leading position in mobile terminals, smart home applications, wireless connectivity technologies and IoT products, with approximately 1.5 billion units a year End products with built-in MediaTek chips are available worldwide.
Several MediaTek chips have a buffer overflow vulnerability in Bluetooth that stems from a lack of bounds checking in Bluetooth. An attacker could exploit the vulnerability to escalate local privileges without requiring user interaction
