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 · unedited
In Plaintext COUNTER CHECK message accepted before AS security activation, there is a possible missing permission check. This could lead to remote information disclosure no additional 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 · moderate confidence

This is a 5G security vulnerability where plaintext COUNTER CHECK messages are accepted by the Access Stratum (AS) before security activation is complete. The missing permission check allows an unauthenticated remote attacker to trigger information disclosure through the Counter Check procedure before cryptographic protections are active.

MitigationImplement proper validation to ensure AS security is fully activated before processing plaintext Counter Check messages; enforce security mode command completion prior to accepting sensitive procedures.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check Android OS version
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB
    Affected if Version is exactly 12.0 or 13.0 (this vulnerability affects only these specific versions)
  2. Verify 5G hardware capability
    Check device specifications or go to Settings > Network & Internet > Mobile Network > Preferred Network Type to see if 5G options are available
    Affected if Device supports 5G (the vulnerability exists in the 5G Access Stratum implementation)
  3. Confirm 5G connectivity is active
    Check the status bar for 5G, LTE, or 5G NR indicator; or go to Settings > Network & Internet > Mobile Network to see if connected
    Affected if Device uses 5G network connection (the flaw is triggered when processing plaintext Counter Check messages over 5G)

If running Android 12.0 or 13.0 on a 5G-capable device that connects to 5G networks, the device is affected because the AS security activation timing check is missing in the 5G protocol implementation.
