CVE-2022-39848

Serial number disclosure via AT_Distributor Logcat entry

Published Oct 7, 2022 · Updated Aug 3, 2024

Sensitive information exposure in AT_Distributor on Samsung Mobile Devices before SMR Oct-2022 Release 1 allows local users to read SerialNo. AT_Distributor writes the device serial number to Logcat, where a local process can retrieve the entry instead of receiving only policy-compatible data. Access requires local execution on an affected Android 10, 11, or 12 device, and the exposed data is limited to the device serial number.
