Name of the Vulnerable Software and Affected Versions Android versions prior to the fixed version

Description The issue is related to a missing permission check in the sendMessage function of OneToOneChatImpl.java, which could allow sending an RCS message without proper permissions. This might lead to local escalation of privilege without requiring additional execution privileges. User interaction is not necessary for exploitation.

Recommendations For Android versions prior to the fixed version, consider restricting access to the sendMessage function in OneToOneChatImpl.java to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
