CVE-2022-39874

Unauthorized logout via undisclosed log-data exposure

Published Oct 7, 2022 · Updated Aug 3, 2024

Sensitive log-data exposure in Samsung Account before 13.5.0 allows local users to force an unauthorized account logout. Samsung identifies excessive logging as the weakness, but neither the CNA record nor the bulletin names the affected log, exposed data, or operation connecting disclosure to logout. Local access is required, and the published impact is limited to information exposure and forced logout; no code execution or broader account control is reported.
