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 ...
[45] [46] It affects certain ARM64 CPUs [47] and the following Intel CPU families: Cascade Lake, Ice Lake, Tiger Lake and Alder Lake. According to Linux kernel developers AMD CPUs are also affected. [48] In March 2022, a vulnerability affecting a wide range of AMD CPUs was disclosed under CVE-2021-26341. [49] [50]
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".
Google says it informed the affected companies about the Spectre flaw on June 1, 2017 and reported the Meltdown flaw after the first flaw but before July 28, 2017.
The Meltdown and Spectre CPU vulnerabilities hung like a shadow over the festivities of CES. What's typically a celebration of consumer electronics was instead a stark reminder of just how far ...

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.
Lazy FPU state leak (CVE-2018-3665), also referred to as Lazy FP State Restore [1] or LazyFP, [2] [3] is a security vulnerability affecting Intel Core CPUs. [1] [4] The vulnerability is caused by a combination of flaws in the speculative execution technology present within the affected CPUs [1] and how certain operating systems handle context switching on the floating point unit (FPU).
