CVE-2022-36856

Emergency-call initiation via undefined permission

Published Sep 9, 2022 · Updated Aug 3, 2024

Improper access control in the Telecom application on Samsung Mobile Devices before SMR Sep-2022 Release 1 allows local users to start emergency calls. The Telecom application accepts an emergency-call request through an undefined permission instead of enforcing a defined permission that restricts the operation. Affected devices run Android 12, and a local caller can trigger emergency-call behavior without the intended permission gate.
