If a patch is available, users should apply the patch as soon as possible. End users of safety-critical systems should contact the manufacturer of their product to obtain a patch.Note: in some cases, manufacturers may need to develop and test their own software patches. Manufacturers of products who develop unique versions of RTOS software should contact BlackBerry to obtain the patch code.Manufacturers of products that incorporate vulnerable versions should contact BlackBerry to obtain the patch. ![]() Table 1: Affected BlackBerry QNX Products ProductĦ.3.0SP3, 6.3.0SP2, 6.3.0SP1, 6.3.0, 6.2.1b, 6.2.1, 6.2.1A, 6.2.0ĬISA strongly encourages critical infrastructure organizations and other organizations developing, maintaining, supporting, or using affected QNX-based systems to patch affected products as quickly as possible. Because many affected devices include safety-critical devices, exploitation of this vulnerability could result in a malicious actor gaining control of sensitive systems, possibly leading to increased risk of damage to infrastructure or critical functions. ![]() See CISA ICS Advisory ICSA-21-119-04 and Microsoft’s BadAlloc blog post for more information.Īll BlackBerry programs with dependency on the C runtime library are affected by this vulnerability (see table 1 for a list of affected BlackBerry QNX products). An attacker with network access could remotely exploit this vulnerability if the vulnerable product is running and the affected device is exposed to the internet.ĬVE-2021-22156 is part of a collection of integer overflow vulnerabilities, known as BadAlloc, which affect a wide range of industries using Internet of Things (IoT), and operational technology (OT)/industrial control systems (ICS) devices. To exploit this vulnerability, an attacker must have control over the parameters to a calloc() function call and the ability to control what memory is accessed after the allocation. Exploitation of this vulnerability could lead to a denial-of-service condition or arbitrary code execution in affected devices. Refer to the Mitigations section for more information about patching.Ĭlick here for a PDF version of this report.ĬVE-2021-22156 is an integer overflow vulnerability affecting the calloc() function in the C runtime library of multiple BlackBerry QNX products. Note: at this time, CISA is not aware of active exploitation of this vulnerability.ĬISA strongly encourages critical infrastructure organizations and other organization developing, maintaining, supporting, or using affected QNX-based systems, to patch affected products as quickly as possible. BlackBerry QNX RTOS is used in a wide range of products whose compromise could result in a malicious actor gaining control of highly sensitive systems, increasing risk to the Nation’s critical functions. A remote attacker could exploit CVE-2021-22156 to cause a denial-of-service condition or execute arbitrary code on affected devices. BadAlloc is a collection of vulnerabilities affecting multiple RTOSs and supporting libraries. On August 17, 2021, BlackBerry publicly disclosed that its QNX Real Time Operating System (RTOS) is affected by a BadAlloc vulnerability-CVE-2021-22156.
