A collection of security flaws in the firmware implementation of 5G mobile network modems from major chipset vendors such as MediaTek and Qualcomm impact USB and IoT modems as well as hundreds of smartphone models running Android and iOS. Of the 14 flaws – collectively called 5Ghoul (a combination of “5G” and “Ghoul”) – 10 […]
A novel hardware attack dubbed PACMAN has been demonstrated against Apple’s M1 processor chipsets, potentially arming a malicious actor with the capability to gain arbitrary code execution on macOS systems. It leverages “speculative execution attacks to bypass an important memory protection mechanism, ARM Pointer Authentication, a security feature that is used to enforce pointer integrity,” […]
U.S. graphics chip specialist NVIDIA has released software updates to address a total of 26 vulnerabilities impacting its Jetson system-on-module (SOM) series that could be abused by adversaries to escalate privileges and even lead to denial-of-service and information disclosure. Tracked from CVE‑2021‑34372 through CVE‑2021‑34397, the flaws affect products Jetson TX1, TX2 series, TX2 NX, AGX […]
One of the reasons why Apple’s iPads and iPhones are considered far superior to its Android counterparts in terms of processing power is their homegrown chips. Apple’s tight integration between hardware and software by placing an in-house chip instead of off-the-shelf parts brings all the difference. Following Apple’s footsteps, Microsoft has now introduced custom-designed chips […]
Qualcomm has announced X55, its second generation 5G modem chip that supports wireless speeds up to 7 Gbps and also supports 4G LTE, 3G, and 2G for the backward compatibility. Qualcomm X55 supports both the 5G bands – mnWave (high-bandwidth) and sub-6GHz (better coverage). To support new chips, the company has also announced a new 5G […]
