Name of the Vulnerable Software and Affected Versions: Android versions Android-11

Description: A missing permission check in the onReceive function of DcTracker.java allows for the potential triggering of a provisioning URL and modification of other telephony settings. This could lead to a local escalation of privilege during the onboarding flow, requiring no additional execution privileges. User interaction is not necessary for exploitation.

Recommendations: For Android version Android-11, consider restricting access to the onReceive function of DcTracker.java until a patch is available. As a temporary workaround, review and limit modifications to telephony settings during the onboarding flow to minimize the risk of exploitation.
