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

Description The issue concerns a side channel information disclosure in the startRanging function of RttServiceImpl.java. This could allow an attacker to determine whether an app is installed without requiring query permissions, potentially leading to local information disclosure. No additional execution privileges are needed, and user interaction is not required for exploitation.

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