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
Improper Input Validation in IpcProtocol in Modem prior to SMR Nov-2024 Release 1 allows local attackers to cause Denial-of-Service.

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 an improper input validation vulnerability in the IpcProtocol component of a modem. Local attackers can send specially crafted IPC messages to trigger a denial-of-service condition, likely causing the modem service to crash or become unresponsive.

MitigationApply the SMR Nov-2024 Release 1 or later vendor firmware update to the affected modem. As a secondary measure, restrict local access to the device to limit attack surface.

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, 13.0, or 14.0 (not newer versions)
  2. Confirm Samsung device with modem
    Verify the device is a Samsung product with cellular modem capability. Check via 'getprop ro.product.brand' and confirm modem hardware exists
    Affected if Device is a Samsung Android phone/tablet with an active modem component
  3. Verify IpcProtocol modem component is present
    Check for the IpcProtocol service or modem IPC daemon. Run 'ps -A | grep -i ipc' or check modem-related processes via 'dumpsys'
    Affected if The IpcProtocol component is running or loaded on the device
  4. Assess local access exposure
    Review if local untrusted processes or apps can send IPC messages to the modem service. Check for exposed IPC sockets or services in /dev/socket or via 'dumpsys' for IPC-related services
    Affected if Local processes have direct access to modem IPC interfaces without proper authentication

The environment is affected if it is a Samsung Android device running version 12.0, 13.0, or 14.0 with the IpcProtocol modem component present and locally accessible to untrusted processes.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the SMR Nov-2024 Release 1 or later vendor firmware update to the affected modem. As a secondary measure, restrict local access to the device to limit attack surface.

Recommended fix Moderate confidence

SMR Nov-2024 Release 1

  1. Check your Samsung device model and carrier for SMR Nov-2024 Release 1 availability
  2. Navigate to Settings > Security and privacy > Security update on your Samsung Android device
  3. Ensure the security patch level shows November 2024 or later
  4. If update is not yet available, periodically check for updates until SMR Nov-2024 Release 1 is delivered
Caveat Samsung monthly security updates typically have no user-facing breaking changes
