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".
In July 2023 a critical vulnerability in the Zen 2 AMD microarchitecture called Zenbleed was made public. [59] AMD released a microcode update to fix it. [60] In August 2023 a vulnerability in AMD's Zen 1, Zen 2, Zen 3, and Zen 4 microarchitectures called Inception [61] [62] was revealed and assigned CVE-2023-20569. According to AMD it is not ...
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 ...
Speculative execution exploit Variant 4, [8] is referred to as Speculative Store Bypass (SSB), [1] [9] and has been assigned CVE-2018-3639. [7] SSB is named Variant 4, but it is the fifth variant in the Spectre-Meltdown class of vulnerabilities.

Retbleed is a speculative execution attack on x86-64 and ARM processors, including some recent Intel and AMD chips. [1] [2] First made public in 2022, it is a variant of the Spectre vulnerability which exploits retpoline, which was a mitigation for speculative execution attacks.

In January 2018, the Meltdown vulnerability was published, known to affect Intel's x86 CPUs and ARM Cortex-A75. [22] [23] It was a far more severe vulnerability than the KASLR bypass that KAISER originally intended to fix: It was found that contents of kernel memory could also be leaked, not just the locations of memory mappings, as previously thought.
