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
Denial of service in MODEM due to reachable assertion while processing configuration from network in Snapdragon Mobile

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 denial of service vulnerability exists in the Qualcomm Snapdragon Mobile modem component where an assertion can be triggered when processing malformed network configuration data. An attacker sending specially crafted configuration messages from the network can cause the modem to crash or become unavailable, affecting voice and data services.

MitigationApply firmware updates provided by device manufacturers as they become available from Qualcomm. Until patches are deployed, monitor network traffic for anomalies targeting modem configuration interfaces.

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 modem firmware version
    Access the device's modem diagnostic interface or use AT commands (such as ATI or AT+GMR) to query the firmware version. On Android devices, this information may also be available under Settings > About Phone > SIM Status or through engineering mode menus.
    Affected if The reported firmware version matches any of the following: Ar8035, Qca8081, Qca8337, Qcn6024, Qcn9024, Sd 8 Gen1 5g, Sdx65, or Wcd9380.
  2. Confirm the chipset vendor
    Check the device specifications or modem documentation to verify the chipset manufacturer is Qualcomm. This may be listed in the device's technical specifications, baseband information, or obtained via AT command responses.
    Affected if The modem uses a Qualcomm Snapdragon or Qualcomm-branded chipset.
  3. Check for network configuration handling
    Verify the device is capable of receiving network configuration data from carrier networks. This is standard for any cellular device that connects to voice or data networks.
    Affected if The device has active cellular connectivity or SIM card functionality, as processing network configuration messages is required for normal operation.

If the device uses any of the listed Qualcomm firmware components (Ar8035, Qca8081, Qca8337, Qcn6024, Qcn9024, Sd 8 Gen1 5g, Sdx65, or Wcd9380) and processes network configuration data, it is affected by this vulnerability.
