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 ...
In 2017, two CPU vulnerabilities (dubbed Meltdown and Spectre) were discovered, which can use a cache-based side channel to allow an attacker to leak memory contents of other processes and the operating system itself. A timing attack watches data movement into and out of the CPU or memory on the hardware running the cryptosystem or algorithm ...
Kernel page-table isolation (KPTI or PTI, [1] previously called KAISER) [2] [3] is a Linux kernel feature that mitigates the Meltdown security vulnerability (affecting mainly Intel's x86 CPUs) [4] and improves kernel hardening against attempts to bypass kernel address space layout randomization (KASLR).
The emergency order in the case brought by 19 state attorneys general said the states "face irreparable harm" because of the risks of disclosing sensitive information and concerns about increased ...
On March 15, 2018, Intel reported that it will redesign its CPUs (performance losses to be determined) to protect against the Spectre security vulnerability, and expects to release the newly redesigned processors later in 2018. [22] [23] On May 3, 2018, eight additional Spectre-class flaws were reported.
A new federal report shows that one drink per day could raise the risk of liver damage and several cancers. The report follows a recommendation by the U.S. Surgeon General on safe alcohol ...
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 ...
