CVE-2023-21446

Local data access via improper input validation

Published Feb 9, 2023 · Updated Mar 24, 2025

Improper input validation in Samsung MyFiles on Android 11 through 13 allows local users to access application data. Samsung identifies missing validation logic as the cause but has not disclosed the input, code locus, or operation that exposes the data. Exploitation is local and requires no user interaction or prior privileges under Samsung's assessment; the reported consequence is read-only data access.
