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 DeregAcceptProcINT of cn_NrmmStateDeregInit.cpp, there is a possible denial of service due to a logic error in the code. This could lead to remote denial of service with no additional execution privileges needed. User interaction is not needed for exploitation.

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

A logic error in the DeregAcceptProcINT function within cn_NrmmStateDeregInit.cpp causes a denial of service condition. The vulnerability allows remote attackers to trigger a DoS without requiring authentication or user interaction, likely due to improper state handling during a deregistration acceptance procedure in what appears to be a telecom/network protocol implementation.

MitigationApply vendor-provided patches for this vulnerability. If no patch is available, implement network-level rate limiting and monitoring to detect and mitigate anomalous deregistration traffic patterns.

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. Identify the Android version in use
    On the Android device, go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shell
    Affected if Any Android version is running, as the affected products list states all versions are impacted
  2. Determine if the device uses IMS (IP Multimedia Subsystem) services
    Check for presence of IMS-related carrier services or IMS stack components on the device. This may be visible in Settings > Network & Internet > Mobile Network > Advanced > IMS settings, or by examining system logs for IMS-related processes
    Affected if The device supports and uses IMS functionality for VoLTE/VoWiFi, as the vulnerable code (cn_NrmmStateDeregInit.cpp) appears to be part of the NRMm state machine for network deregistration procedures in telecom protocols
  3. Check for anomalous mobile network behavior
    Monitor device logs (logcat) or network traffic for unexpected deregistration messages or frequent loss of cellular service, particularly involving the deregistration acceptance procedure
    Affected if The device experiences repeated or unexpected network deregistration events that could indicate exploitation of the logic error in DeregAcceptProcINT
  4. Review carrier/ROM build for telecom component patches
    If available, examine the build fingerprint or carrier firmware version for any applied security patches related to telecom/network protocol handling. Check getprop for relevant system properties
    Affected if The build does not contain specific patches addressing the cn_NrmmStateDeregInit.cpp vulnerability in the deregistration state machine

Since all Android versions are listed as affected, the primary condition for impact is simply running any Android device that utilizes IMS-based cellular services, with the vulnerability residing in the telecom stack's deregistration acceptance state handling logic.
