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 · uneditedLogic error in package installation via adb command prior to SMR Jul-2023 Release 1 allows local attackers to downgrade installed application.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA logic error in Samsung's package installation mechanism via ADB (Android Debug Bridge) allows a local attacker with physical device access to downgrade installed applications to older versions, potentially reintroducing known vulnerabilities. The flaw exists in the SMR (Samsung Monthly Release) versions prior to July 2023 Release 1.

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.
-
Check Android versionRun 'adb shell getprop ro.build.version.release' or go to Settings > About Phone > Android versionAffected if Version shows 12.0 or 13.0 (these are the affected Android versions)
-
Check Samsung SMR versionRun 'adb shell getprop ro.build.version.smr' or go to Settings > About Phone > Software information > Samsung Android versionAffected if SMR version is earlier than Jul-2023 Release 1 (for example, shows Jun-2023 or earlier)
-
Confirm SMR release dateRun 'adb shell getprop ro.build.version.smr' and parse the date code (format typically shows month-year like '06-2023')Affected if The SMR date code is before July 2023 (e.g., 06-2023, 05-2023, etc.)
-
Verify ADB debugging is accessibleRun 'adb devices' from a host machine or check Settings > Developer options > USB debugging is enabledAffected if ADB debugging is enabled and the device is vulnerable per the SMR version check
A user is affected if their Samsung device runs Android 12.0 or 13.0 with an SMR version dated before July 2023 Release 1 and has ADB debugging accessible.

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 Samsung SMR Jul-2023 Release 1 or later security update to affected devices to patch the logic error in package installation.
SMR Jul-2023 Release 1 (July 2023 Samsung Security Maintenance Release)
- On the Samsung Galaxy device, open Settings
- Navigate to Software Update
- Tap Download and install to check for and apply the July 2023 security update (SMR Jul-2023 Release 1)
