CVE-2024-38426
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 · uneditedWhile processing the authentication message in UE, improper authentication may lead to information disclosure.
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 confidenceDuring authentication message processing in User Equipment (UE), improper authentication implementation may allow an attacker to potentially obtain sensitive information through the authentication flow.

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.
-
Identify Qualcomm firmware components in your environmentInventory your network devices, IoT devices, and embedded systems to identify which ones use the affected Qualcomm firmware products: 315 5G IoT, 9205 LTE, AR8035, CSRA6620, CSRA6640, CSRB31024, FastConnect 6200, or FastConnect 6700. Check device documentation, firmware images, or system information for Qualcomm component identifiers.Affected if Any device in your environment uses one of the listed Qualcomm firmware products.
-
Verify the specific Qualcomm chip/module modelLocate the exact model number of the Qualcomm chip or module in your devices. This is typically found in device hardware specifications, FCC filings, firmware build information, or by querying the device's AT command interface (for modems).Affected if The identified chip/module matches one of: 315 5G IoT, 9205 LTE, AR8035, CSRA6620, CSRA6640, CSRB31024, FastConnect 6200, FastConnect 6700.
-
Confirm firmware versionRetrieve the installed firmware version from the device. For modem/firmware components, this is often done via AT commands (e.g., AT+CGMR), through the device's web UI, or by extracting firmware from the device. Compare against the affected product list.Affected if The device runs any firmware version on the listed Qualcomm products, as all versions are affected per the advisory.
-
Determine if device processes authentication messagesConfirm whether the device uses its Qualcomm modem component for cellular, Wi-Fi, or other network authentication. These firmware products are designed for cellular IoT modems (315, 9205), ethernet PHYs (AR8035), Bluetooth audio (CSRA series), and Wi-Fi (FastConnect series), all of which handle authentication flows.Affected if The device uses the Qualcomm component for any network authentication functionality (cellular registration, Wi-Fi authentication, Bluetooth pairing).
If your environment contains any device using the Qualcomm 315 5G IoT, 9205 LTE, AR8035, CSRA6620, CSRA6640, CSRB31024, FastConnect 6200, or FastConnect 6700 firmware for authentication processing, you are affected since all versions of these products are vulnerable.

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.
From vendor dataImplement proper authentication validation and ensure secure handling of authentication messages in UE to prevent information disclosure.
