CVE-2021-35079

Local information disclosure via unchecked Telephony permissions

Published Jun 14, 2022 · Updated Aug 4, 2024

Permission validation failure in Qualcomm Snapdragon Telephony API allows local users to obtain protected information through a third-party app. The service accepts API access without properly confirming the caller's required permissions; Qualcomm has not disclosed the exact check or returned data. A local third-party application must invoke the Telephony service, and the documented consequence is limited to information disclosure.
