Call-information disclosure via missing IImsService permission
Published Nov 9, 2022 · Updated May 1, 2025
Improper access control in IImsService on Samsung Mobile Devices Q(10), R(11), and S(12) allows local users to read call information. The service exposes call data without the permission that the November 2022 patch adds to block unauthorized access. A malicious application running locally can reach the unprotected service; the reported consequence is limited to call-information disclosure.
