CVE-2021-25357
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 · uneditedA pendingIntent hijacking vulnerability in Create Movie prior to SMR APR-2021 Release 1 in Android O(8.x) and P(9.0), 3.4.81.1 in Android Q(10,0), and 3.6.80.7 in Android R(11.0) allows unprivileged applications to access contact information.
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 confidenceThis is a PendingIntent hijacking vulnerability in Samsung's Create Movie application. A PendingIntent is an intent that can be passed to another application to execute with the creator's permissions. When hijacked, an unprivileged local application can intercept or manipulate this intent to access contact information that should have been protected.

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.
-
Identify Android versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if The version is 8.1 or 9.0 exactly
-
Locate the Create Movie applicationCheck if 'Create Movie' or 'com.samsung.android.app.movie' is installed by reviewing installed packages via ADB command 'pm list packages | grep -i movie' or checking the app drawerAffected if The Create Movie application is present on the device
-
Verify Samsung security patch levelGo to Settings > About Phone > Software information > Security patch level, or run 'getprop ro.build.version.security_patch' via ADB shellAffected if The security patch level is earlier than April 2021 (patch date is blank, shows a date before 2021-04-01, or does not include the April 2021 Samsung SMR update)
A device is affected if it runs Android 8.1 or 9.0, has the Samsung Create Movie app installed, and lacks the April 2021 Samsung security update.

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.
From vendor dataApply the Samsung SMR (Security Maintenance Route) April 2021 update or later for affected Android versions. Verify the patch has been applied via system settings and test that unprivileged applications can no longer access contact data through the Create Movie component.
