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 · uneditedIn the Phone app, there is a possible crash loop due to resource exhaustion. This could lead to local persistent denial of service in the Phone app with User execution privileges needed.

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 resource exhaustion vulnerability in the Android Phone app causes a persistent crash loop, leading to local denial of service. The issue requires user execution privileges but needs no user interaction to trigger, resulting in the Phone app becoming repeatedly unresponsive.

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 OS versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if Android version is exactly 13.0 (not 13.0.1, 13.0.2, or other versions)
-
Confirm Phone app is installedCheck if com.android.phone package exists in Settings > Apps, or run 'pm list packages | grep com.android.phone' via ADB shellAffected if The Phone application is installed and enabled on the device
-
Check for Phone app crash behaviorRun 'dmesg' via ADB shell or check Android Bugreport for Phone app crash logs, or monitor with 'adb logcat' looking for frequent Phone process restartsAffected if The Phone app is experiencing repeated crash loops or resource exhaustion indicators
Device is affected if running Android exactly version 13.0 and the Phone app is present, exhibiting persistent crash loops or unresponsiveness.

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 Android-13 security patch containing the fix for this vulnerability; users should ensure their devices receive regular system updates.
Android 13.0 update (13.0.1 or later) or Android 14
- 1. Navigate to Settings > System > System Update on the affected Android 13.0 device
- 2. Check for and install any available system updates
- 3. Alternatively, upgrade to Android 14 or later if available for your device
