A major vulnerability affecting older versions of BlackBerry's QNX Real-Time Operating System (RTOS) could allow malicious actors to cripple and gain control of a variety of products, including cars, medical, and industrial equipment. The shortcoming (CVE-2021-22156, CVSS score: 9.0) is part of a broader collection of flaws, collectively dubbed  BadAlloc , that was originally disclosed by Microsoft in April 2021, which could open a backdoor into many of these devices, allowing attackers to commandeer them or disrupt their operations. "A remote attacker could exploit CVE-2021-22156 to cause a denial-of-service condition or execute arbitrary code on affected devices," the U.S. Cybersecurity and Infrastructure Security Agency (CISA)  said  in a Tuesday bulletin. As of writing, there is no evidence of active exploitation of the vulnerability. BlackBerry QNX technology is  used  worldwide by over 195 million vehicles and embedded systems across a wide range of industries,

Security researchers have discovered almost a dozen zero-day vulnerabilities in VxWorks, one of the most widely used real-time operating systems (RTOS) for embedded devices that powers over 2 billion devices across aerospace, defense, industrial, medical, automotive, consumer electronics, networking, and other critical industries. According to a new report Armis researchers shared with The Hacker News prior to its release, the vulnerabilities are collectively dubbed as URGENT/11 as they are 11 in total, 6 of which are critical in severity leading to 'devastating' cyberattacks. Armis Labs is the same IoT security company that previously discovered the BlueBorne vulnerabilities in Bluetooth protocol that impacted more than 5.3 Billion devices—from Android, iOS, Windows and Linux to the Internet of things (IoT). These vulnerabilities could allow remote attackers to bypass traditional security solutions and take full control over affected devices or "cause disruption on
