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

Description The issue is related to a permissions bypass in the smsSelected function of AnswerFragment.java, allowing an SMS to be sent from the lock screen. This could lead to a local escalation of privilege on the lock screen without requiring additional execution privileges. User interaction is necessary for exploitation.

Recommendations For Android version Android-10, consider restricting access to the smsSelected function of AnswerFragment.java to minimize the risk of exploitation until a patch is available. As a temporary workaround, disabling the SMS functionality from the lock screen may also help mitigate the issue.
