Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Exynos 2200 processor is in useCheck device specifications or use a system info app to identify the processor model number. Exynos 2200 is found in certain regional variants of Samsung Galaxy S22 series and Galaxy Tab S8 series.Affected if The device contains an Exynos 2200 processor
-
Check Android Security Patch LevelGo to Settings > About Phone > Software Information > Security Patch Level. This date indicates when the most recent Android security updates (including firmware-level fixes) were applied.Affected if The Security Patch Level is earlier than May 2025, when the fix for this CVE would have been released
-
Check Samsung firmware versionIn Settings > About Phone > Software Information, note the firmware version. Cross-reference with Samsung's official firmware release notes for your specific model to see if a version after the CVE disclosure date has been installed.Affected if The installed firmware version predates the CVE-2025-23104 patch release for your specific device model
-
Verify CVE inclusion in applied updatesReview the Android Security Bulletin for the month of the applied patch and confirm CVE-2025-23104 is listed as addressed for the Exynos 2200 component.Affected if The CVE is not listed as resolved in the Security Patch Level currently installed
A user is affected if their device contains an Exynos 2200 processor and lacks the firmware/security patch that addresses CVE-2025-23104, typically indicated by a Security Patch Level before May 2025.
