CVE-2023-42542

Device identification via unchecked register ID access

Published Nov 7, 2023 · Updated Mar 6, 2025

Improper access control in Samsung Push Service before 3.4.10 allows local users to read a register ID that identifies the device. Samsung identifies no specific interface or function, but states that the vulnerable code omits a proper access-control check before returning the identifier. Exploitation requires a locally installed, low-privilege application and discloses a device identifier without altering data or interrupting service.
