Base vector

AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions Android versions Android-10 through Android-12L

Description The issue is related to a missing permission check in the setScanMode function of AdapterService.java, which could allow enabling Bluetooth discovery mode without user interaction. This might lead to local escalation of privilege, requiring User execution privileges for exploitation. User interaction is necessary for this issue to be exploited.

Recommendations For Android versions Android-10 through Android-12L, consider restricting access to the setScanMode function in AdapterService.java until a patch is available. As a temporary workaround, disabling Bluetooth discovery mode by default could minimize the risk of exploitation.
