In March 2024, a variant of Spectre-V1 attack called GhostRace was published. [70] It was claimed it affected all the major microarchitectures and vendors, including Intel, AMD and ARM. It was assigned CVE-2024-2193. AMD dismissed the vulnerability (calling it "Speculative Race Conditions (SRCs)") claiming that existing mitigations were enough ...
Intel's Software Guard Extensions (SGX) security subsystem is also affected by this bug. [4]The Downfall vulnerability was discovered by the security researcher Daniel Moghimi, who publicly released information about the vulnerability in August 2023, after a year-long embargo period.
Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...

The HX processors only support: DDR5-4800 (DDR5-5600 for i7-13850HX and above), DDR4-3200. The processors are connected to PCHs using an OPIO 2.0 x8 interface, except for the HX series which uses a DMI 4.0 x8 interface. [29] Except for the HX series, the processor and PCH are packaged together on a multi-chip package.

The vulnerability is known to affect Skylake and later processors from Intel and Zen-based processors from AMD. [ 54 ] In February 2023, a team of researchers at North Carolina State University uncovered a new code execution vulnerability called Spectre-HD, also known as "Spectre SRV" or "Spectre v6".
Reptar is a CPU vulnerability discovered in late 2023, affecting a number of recent families of Intel x86 CPUs. According to The Register, the following CPU families are vulnerable: Alder Lake, Raptor Lake and Sapphire Rapids. [1] The Reptar vulnerability relates to processing of x86 instruction prefixes in ways that lead to unexpected behavior ...
