VAIO News - Infineon TPM vulnerability in VAIO Pro 13/11 series

Applicable Products and Categories of This Article

What is the matter with the Infineon chip?

Infineon Technologies, a semiconductor manufacturer, identified a security vulnerability in its TPM (Trusted Platform Module) security chip.

Sony would like to notify the owners of certain VAIO Pro 13/11 series notebook computers that their device is equipped with this TPM chip.

Since this TPM chip does not properly generate encryption keys, the risk of decryption increases. In other words, this vulnerability weakens key strength.

For more details you can visit the Infineon dedicated page.  


What will Sony provide as a countermeasure?

Sony is currently working together with Infineon on a solution. In the future we will provide a program update to solve this vulnerability.

Nonetheless, we expect that this will take some time, so we will inform you as soon as the program update is ready.

Please bookmark and visit this page regularly to receive future updates.

We sincerely apologise for any inconvenience this issue may cause and thank you for your kind understanding and cooperation.


What can I currently do if my notebook is affected?

Because the encryption is still effective to a certain extent, we believe that you can continue to use your notebook.

However, please ensure that you've installed appropriate forms of PC theft prevention and anti-virus measures.


Affected models

The following Sony VAIO Pro series, launched between June 2013 and February 2014, might be affected.

  • SVP11 Series
  • SVP13 Series

Note that not every model of this series is equipped with Infineon's TPM chip.

You can find a detailed list at the bottom of this article.

You can use our support page to find out where you can find your model name.

 


How can I confirm if my model is affected?

  1. Hold down the [Windows] key and press the [R] key. The [Run] dialogue box will open up.
    (Alternatively, type the [Run] command in the Windows [Start] search menu)

    Run command prompt

  2. In the [Run] dialog box, enter [tpm.msc] and select [OK].

    tpm msc in run prompt

 

Possible outcomes

Result 1: "Compatible TPM cannot be found"

If your notebook is not equipped with the affected TPM chipset, the message [Compatible TPM cannot be found] will be displayed, and therefore your notebook computer is not affected by this issue.

TPM cannot be found

 
Result 2: Manufacturer version equals 4.31 or 4.32

A [TPM Management on Local Computer] screen will appear. You can find the TPM Manufacturer information located at the bottom of this screen (see screenshot at result 3).

If the manufacturer's version indicates "4.31" or "4.32", the affected Infineon TPM chipset is installed.

This means that your notebook computer is affected by the vulnerability issue.
Please bookmark this page and return for future updates.

Result 3: Manufacturer version does not equal 4.31 or 4.32

A [TPM Management on Local Computer] screen will appear. You can find the TPM Manufacturer information located at the bottom of this screen (see screenshot below).

If other versions than "4.31" or "4.32", are displayed, your notebook is not affected.
