CVE-2021-25486

Device-information disclosure via unrestricted ipcdump logs

Published Oct 6, 2021 · Updated Aug 3, 2024

Information exposure in ipcdump on Samsung Mobile Devices before SMR Oct-2021 Release 1 allows local users to obtain device information. Affected releases expose packet-derived device information in ipcdump logs without enforcing access control on the utility. Low-privileged local access is required; the documented consequence is read-only disclosure of device information, not modification or service interruption.
