CVE-2022-20244

Status: ModifiedHigh (7.5)—

In Bluetooth, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege if more than 100 bluetooth devices have been connected with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-13Android ID: A-201083240
