AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N

Name of the Vulnerable Software and Affected Versions Android versions Android-12

Description The issue is related to a side channel information disclosure in the getNetworkTypeForSubscriber function of PhoneInterfaceManager.java. This could allow an app to determine whether another 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 version Android-12, consider restricting access to the getNetworkTypeForSubscriber function of PhoneInterfaceManager.java to minimize the risk of exploitation. As a temporary workaround, avoid using sensitive information that could be disclosed through this side channel until a patch is available.
