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 configuration vulnerability exists when loading a 3rd-party QTEE application.

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 configuration vulnerability in Qualcomm Android devices with Linux kernel allows 3rd-party applications to be loaded into the QTEE (Qualcomm Trusted Execution Environment). This could enable untrusted code to execute within a trusted security context, potentially bypassing TEE security boundaries.

MitigationApply vendor-provided patches/updates from Qualcomm and device manufacturers. Until patches are available, avoid loading or installing untrusted 3rd-party applications that request QTEE access.

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 device processor architecture
    Check if the device uses a Qualcomm Snapdragon processor. On Android, this can be done by checking /proc/cpuinfo or using a system information app to view processor details.
    Affected if The device uses a Qualcomm processor and runs Android - this is a prerequisite for the QTEE vulnerability.
  2. Verify QTEE presence
    Check if the Qualcomm Trusted Execution Environment (QTEE) is present on the device. This may be indicated by the presence of tee* services in /proc/ or by checking for qsee* or tee* entries in /sys/kernel/debug/ if debugging is enabled.
    Affected if QTEE is present on the device, making the configuration vulnerability applicable.
  3. Assess TEE application loading policy
    Examine whether the device allows loading 3rd-party applications into the TEE context. This typically requires checking TEE daemon configuration or permissions related to the trusted application framework.
    Affected if 3rd-party applications are permitted to be loaded into the QTEE context, which is the vulnerable configuration described in this CVE.

The user is affected if they are running Android on a Qualcomm-based device where 3rd-party applications can be loaded into the QTEE, as this allows untrusted code to execute within the trusted security boundary.

Mitigation

Apply vendor-provided patches/updates from Qualcomm and device manufacturers. Until patches are available, avoid loading or installing untrusted 3rd-party applications that request QTEE access.
