In the ioctl handlers of the Mediatek Command Queue driver, there is a possible out of bounds write due to insufficient input sanitization and missing SELinux restrictions. This could lead to local escalation of privilege with no additional execution privileges needed.

Honor 10 Lite, Honor 8A, Huawei Y6 mobile phones with the versions before 9.1.0.217(C00E215R3P1), the versions before 9.1.0.205(C00E97R1P9), the versions before 9.1.0.205(C00E97R2P2) have an information leak vulnerability. Due to improper function error records of some module, an attacker with the access permission may exploit the vulnerability to obtain some information.

A flaw was discovered in the Bluetooth protocol. An attacker within physical proximity to the Bluetooth connection could downgrade the encryption protocol to be trivially brute forced.
