QNX BLACKBERRY CODE

This vulnerability could allow remote code execution or denial-of-service attacks.

Further advice for supply chain risk management can be found in the Cyber Supply Chain Risk Management Practitioner Guide publication.Īn integer overflow vulnerability exists in BlackBerry’s QNX products (including standard, medical and safety-certified versions).

When remote access is required, apply the ACSC Industrial Control Systems Remote Access Protocol publication.

Locate control system networks and remote devices behind firewalls, and isolate them from the business network.

Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet.

QNX BLACKBERRY PATCH

End users should contact the manufacturer of their product to obtain a patch and apply the patch as soon as possible.

QNX BLACKBERRY SOFTWARE

Manufacturers of products who develop unique versions of RTOS software should contact BlackBerry to obtain the patch code but may need to develop and test their own software patches.

Manufacturers of products that incorporate vulnerable versions should contact BlackBerry or their direct reseller to obtain the patch code.

The ACSC recommends users take defensive measures such as those detailed in the Protecting Industrial Control Systems publication to minimize the risk of exploitation. Whether exploitation is possible depends on the presence of an external connection, and whether compensating controls otherwise protect the device. Other devices might require reviewing the product specification sheet or a discussion with the vendor. Some devices might have an ‘about page’ or software ‘information pages’ that detail the underlying real time operating system. When such systems are identified, they should be investigated to see if they are running QNX and the risk assessed. Individual work areas may need to be asked where they have safety critical systems, or where a real-time operating system would need to be deployed. The ACSC suggest users identify where the BlackBerry QNX real time operating system is used in their systems. BadAlloc is a collection of vulnerabilities affecting multiple RTOS and supporting libraries used in a wide range of industries using Internet of Things (IoT), medical devices, and operational technology (OT)/industrial control systems (ICS) devices. QNX is the world’s most prevalent real time operating system. If you have questions about this cybersecurity vulnerability, contact the Cybersecurity and Infrastructure Security Agency (CISA).On August 17, 2021, BlackBerry publicly disclosed that its QNX Real Time Operating System is affected by a BadAlloc vulnerability - CVE-2021-22156. Drug manufacturers regulated by the Center for Drug Evaluation and Research should contact: Please include the product(s), equipment, and/or system(s) that use the vulnerable RTOS and any identified or possible impacts. If your organization is impacted by the BlackBerry QNX cybersecurity vulnerability, please contact FDA.

Manufacturers are assessing which equipment or systems may be affected by the BlackBerry QNX cybersecurity vulnerability, evaluating the risk, and developing mitigations, including deploying patches from BlackBerry. FDA is not aware of any confirmed adverse events related to these vulnerabilities. These vulnerabilities may introduce risks for certain medical devices and drug manufacturing equipment. Food and Drug Administration is informing patients, health care providers, and manufacturers about cybersecurity vulnerabilities with a “real-time operating system (RTOS)” designed by QNX and owned by BlackBerry.
