New 5G Modem Flaws Affect iOS Devices and Android Models from Major Brands

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 affect 5G modems from the two companies, out of which three

Collide+Power, Downfall, and Inception: New Side-Channel Attacks Affecting Modern CPUs

Cybersecurity researchers have disclosed details of a trio of side-channel attacks that could be exploited to leak sensitive data from modern CPUs. Called Collide+Power (CVE-2023-20583), Downfall (CVE-2022-40982), and Inception (CVE-2023-20569), the novel methods follow the disclosure of another newly discovered security vulnerability affecting AMD's Zen 2 architecture-based processors known as 

New 'Retbleed' Speculative Execution Attack Affects AMD and Intel CPUs

Security researchers have uncovered yet another vulnerability affecting numerous older AMD and Intel microprocessors that could bypass current defenses and result in Spectre-based speculative-execution attacks. Dubbed Retbleed by ETH Zurich researchers Johannes Wikner and Kaveh Razavi, the issue is tracked as CVE-2022-29900 (AMD) and CVE-2022-29901 (Intel), with the chipmakers releasing software

MIT Researchers Discover New Flaw in Apple M1 CPUs That Can't Be Patched

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," MIT
