Base vector

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

Name of the Vulnerable Software and Affected Versions: Android version Android-11

Description: In the onReceive method of ImsPhoneCallTracker.java, there is a possible misattribution of data usage due to an incorrect broadcast handler. This could lead to local escalation of privilege, resulting in attributing video call data to the wrong app, with no additional execution privileges needed. User interaction is not needed for exploitation.

Recommendations: For Android version Android-11, consider restricting access to the ImsPhoneCallTracker.java module to minimize the risk of exploitation until a patch is available. As a temporary workaround, review and adjust broadcast handlers to prevent incorrect data attribution.
