Intel has divulged more details on its Raptor Lake family of 13th and 14th Gen Core processor failures and the 0x129 microcode that's supposed to prevent further damage from occurring. The chipmaker previously disclosed that the so-called instability issue plaguing many Raptor Lake chips stems from an elevated operating voltage set by the processor itself.
Modern CPUs from Intel, including Raptor Lake and Alder Lake, have been found vulnerable to a new side-channel attack that could be exploited to leak sensitive information from the processors. The...
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.

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.
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.
Cybersecurity researchers have disclosed details of a now-patched security flaw in Phoenix SecureCore UEFI firmware that affects multiple families of Intel Core desktop and mobile processors....
