CVE-2022-27836
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper access control and path traversal vulnerability in Storage Manager and Storage Manager Service prior to SMR Apr-2022 Release 1 allow local attackers to access arbitrary system files without a proper permission. The patch adds proper validation logic to prevent arbitrary files access.

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.
-
Verify Android version is 12.0Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADBAffected if Android version equals 12.0 specifically (not 11 or 13)
-
Confirm device is a Samsung Galaxy modelCheck Settings > About Phone > Model name, or run 'getprop ro.product.model' via ADBAffected if Device is a Samsung Galaxy device running the affected Android version
-
Check Samsung Security Patch LevelGo to Settings > About Phone > Software information > Security patch level, or run 'getprop ro.build.version.security_patch' via ADBAffected if Security patch level is earlier than April 2022 (e.g., March 2022 or older)
-
Verify Storage Manager service presenceRun 'pm list packages | grep samsung' and look for packages containing 'storagemanager', or check for 'com.samsung.android.storagemanager' via ADBAffected if Samsung Storage Manager package is installed on the device
Device is likely affected if it is a Samsung Galaxy running Android 12.0 with a Security Patch Level before April 2022 and has the Samsung Storage Manager service present.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply the SMR Apr-2022 Release 1 patch which adds proper path validation logic to prevent unauthorized file access. This is a local vulnerability requiring local access to the device.
SMR Apr-2022 Release 1
- Identify the Samsung device model and current Android/SMR version
- Navigate to Settings > About Phone > Software Update on the device
- Check for and install the latest Samsung security update
- Verify the device has updated to SMR Apr-2022 Release 1 or later
