Since Spectre represents a whole class of attacks, most likely, there cannot be a single patch for it. [3] While work is already being done to address special cases of the vulnerability, the original website devoted to Spectre and Meltdown states, "As [Spectre] is not easy to fix, it will haunt us for a long time."
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 ...
Speculative Store Bypass (SSB) (CVE-2018-3639) is the name given to a hardware security vulnerability and its exploitation that takes advantage of speculative execution in a similar way to the Meltdown and Spectre security vulnerabilities. [1]
The latest Windows 10 Insider Preview build includes the latest batch of redesigned folders for the platform.
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 ...
SWAPGS, also known as Spectre variant 1, is a computer security vulnerability that utilizes the branch prediction used in modern microprocessors. [1] [2] [3] Most processors use a form of speculative execution, this feature allows the processors to make educated guesses about the instructions that will most likely need to be executed in the near future.
An official document from ARM informs that all ARM CPUs affected by Spectre are also affected by Retbleed. [2] Windows is not vulnerable because the existing mitigations already tackle it. [1] Linux kernels 5.18.14 and 5.19 contain the fixes. [5] [6] The 32-bit Linux kernel, which is vulnerable, will not receive updates to fix the issue. [7]
