CVE-2022-23426

System-privileged file access via PendingIntent hijacking

Published Feb 11, 2022 · Updated Aug 3, 2024

PendingIntent hijacking in Samsung Mobile Devices before SMR Feb-2022 Release 1 allows local users to access files with system privilege. DeX Home and DeX for PC expose a PendingIntent without protecting its recipient, allowing an unprivileged application to hijack the delegated operation. The attack requires local code execution and user interaction; successful exploitation crosses the DeX privilege boundary and grants system-context file access.
