![]() ![]() We have seen no reports of active exploitation, though we encourage end users to update their devices with patches available from OEMs. The vulnerabilities publicized by Check Point have been patched, one in early October 2019 and the other in November 2014. Providing technologies that support robust security and privacy is a priority for Qualcomm. In a statement to BleepingComputer, a Qualcomm spokesperson told, Right when this report surfaced online, Qualcomm confirmed that they have already fixed the vulnerabilities. However, it took months for the vendors to confirm a fix. Though, they immediately informed Qualcomm of the flaws. They could find vulnerabilities affecting Samsung, Motorola, and LG devices. Patched Already Delivered To OEMsĬheck Point found this vulnerability (CVE-2019-10574) in June. More technical details about the vulnerability are available in their report. These include Security Monitor Call (SMC) handlers that load trusted apps and redirect commands from Normal world to trusted apps, and Trusted apps’ command handlers that load data blob from the Normal world. The researchers highlighted two main components of TEE code, targeting which can lead to exploits. However, due to a flaw, an attacker can gain access to all this information by trusted app-fuzzing. The security extension only allows some specific trusted apps to access this data. ![]() According to the researchers,Ī vulnerability in a component of TEE may lead to leakage of protected data, device rooting, bootloader unlocking, execution of undetectable APT, and more. This secure implementation, as a standard, encloses sensitive device data in a ‘secure world’ by disallowing most apps. In brief, the bug exists in how Qualcomm implements the Trusted Execution Environment (TEE) based on ARM TrustZone. The vulnerability, when exploited, can leak sensitive device information to an attacker. As elaborated in a report, the researchers found a vulnerability in the Qualcomm TEE implementation in Android devices. Qualcomm Bug In Android PhonesĪ Check Point Researcher has recently shared its findings regarding a serious security issue troubling numerous Android phones. ![]() Recently a Qualcomm TEE bug has made these phones vulnerable to cyber attack. Qualcomm CPUs empower most Android phones today. ![]()
