Latest Intel CPUs impacted by new Indirector side-channel attack
2024-07-01 14:24

Modern Intel processors, including chips from the Raptor Lake and the Alder Lake generations are susceptible to a new type of a high-precision Branch Target Injection attack dubbed 'Indirector,' which could be used to steal sensitive information from the CPU. Indirector exploits flaws in Indirect Branch Predictor and Branch Target Buffer, two hardware components found in modern Intel CPUs, to manipulate speculative execution for data extraction. The Indirect Branch Predictor is designed to predict the target addresses of indirect branches using historical execution information, while the Branch Target Buffer predicts the target addresses of direct branches using a set-associative cache structure.

Intel-powered computers affected by serious firmware flaw (CVE-2024-0762)
2024-06-21 11:30

A vulnerability in the Phoenix SecureCore UEFI, which runs on various Intel processors, could be exploited locally to escalate privileges and run arbitrary code within the firmware during runtime. "This type of low-level exploitation is typical of firmware backdoors that are increasingly observed in the wild," Eclypsium researchers noted.

Phoenix UEFI vulnerability impacts hundreds of Intel PC models
2024-06-20 21:31

A newly discovered vulnerability in Phoenix SecureCore UEFI firmware tracked as CVE-2024-0762 impacts devices running numerous Intel CPUs, with Lenovo already releasing new firmware updates to resolve the flaw. Due to the large number of Intel CPUs using this firmware, the vulnerability has the potential to impact hundreds of models from Lenovo, Dell, Acer, and HP. UEFI firmware is considered more secure as it includes Secure Boot, which is supported by all modern operating systems, including Windows, macOS, and Linux.
