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 all Qualcomm products with Android releases from CAF using the Linux kernel, a vulnerability exists in the processing of certain responses from the USIM.

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

Vulnerability in Qualcomm Android products with Linux kernel from CAF in processing certain USIM (Universal Subscriber Identity Module) responses. The flaw exists in the baseband/firmware layer that handles communication with the SIM card, allowing potentially malicious SIM responses to trigger memory corruption or improper handling.

MitigationApply vendor-provided firmware updates from Qualcomm and/or device OEMs. This is a baseband firmware issue requiring coordinated carrier/vendor patch deployment - no user-level remediation is possible.

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 Qualcomm baseband processor
    Check if the device uses a Qualcomm chipset/baseband. This can be done via device info apps or by checking the phone's baseband version in Settings > About Phone > Baseband version. Qualcomm baseband typically shows version strings starting with 'M' or 'MSM'.
    Affected if The device does not use a Qualcomm baseband processor - this vulnerability only affects devices with Qualcomm baseband/firmware.
  2. Check baseband firmware version
    Dial *#*#4636#*#* or use a baseband info app to display the baseband version. Record the full version string shown (e.g., MPSS.DI, or similar Qualcomm firmware identifiers).
    Affected if Unable to determine the baseband version - without knowing the installed baseband firmware version, the exposure status cannot be confirmed.
  3. Verify USIM/SIM functionality is enabled
    Confirm the device has an active USIM or SIM card slot and that SIM communication is functional. This vulnerability applies to devices that process USIM responses - if the device has no SIM capability, it is not affected.
    Affected if The device has no SIM/USIM card capability or SIM communication is disabled - the flaw requires active SIM card interaction to be triggered.
  4. Consult carrier or OEM for patch status
    Contact the device manufacturer or mobile carrier to inquire whether the specific baseband firmware version has received the Qualcomm fix for this issue. Provide the baseband version string obtained in step 2.
    Affected if The carrier or OEM confirms the baseband firmware is unpatched - this is a firmware-level vulnerability that requires vendor-provided updates.

A user is affected if they have a Qualcomm baseband device with an unpatched baseband firmware version that processes USIM responses, as this is a firmware-layer flaw not detectable through Android OS version checks alone.
