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
Memory corruption in Trusted Execution Environment while deinitializing an object used for license validation.

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

Memory corruption vulnerability in the Trusted Execution Environment (TEE) occurring during the deinitialization phase of an object used for license validation. The issue likely involves improper memory cleanup (possibly use-after-free or double-free) when the license validation object is being destroyed, leading to potential code execution or denial-of-service.

MitigationApply vendor-provided patches to the TEE component; ensure the license validation object's memory is properly zeroed and freed during deinitialization with correct synchronization to prevent race conditions.

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 TEE component usage
    Determine if your system contains any of the following Qualcomm firmware components: Ar8035, Fastconnect 6900, Fastconnect 7800, Flight Rb5 5g Platform, Qam8295p, Qca6391, Qca6574au, or Qca6595. Consult your device firmware documentation, bill of materials, or system hardware specifications.
    Affected if Any of the listed Qualcomm components are present in the system
  2. Verify TEE is enabled
    Check if the Trusted Execution Environment is active on the device. This may be observable through system logs, tee-supplicant status, or firmware configuration files indicating TEE initialization.
    Affected if TEE is enabled and running on the device
  3. Confirm license validation functionality exists
    Inspect the firmware or software stack for the presence of license validation routines or modules that interact with the TEE. This may be identifiable through binary analysis, module listings, or license manager logs.
    Affected if License validation objects or modules are present in the firmware
  4. Check firmware version
    Retrieve the installed firmware version for the identified Qualcomm component via device management interfaces, firmware dumping tools, or system information commands.
    Affected if The firmware version corresponds to any of the affected products listed (all versions are impacted)

If your system uses any of the affected Qualcomm firmware components (Ar8035, Fastconnect 6900/7800, Flight Rb5 5g, Qam8295p, Qca6391, Qca6574au, Qca6595) with TEE and license validation enabled, you are likely affected by this vulnerability.
