Name of the Vulnerable Software and Affected Versions Android versions Android-13

Description In Telephony, there is a possible way to determine whether an app is installed, without query permissions, due to side channel information disclosure. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

Recommendations For Android version Android-13, consider restricting access to sensitive information until a patch is available. As a temporary workaround, review and limit the use of Telephony features to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
