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). [2]
Also in August 2023 a new vulnerability called Downfall or Gather Data Sampling was disclosed, [63] [64] [65] affecting Intel CPU Skylake, Cascade Lake, Cooper Lake, Ice Lake, Tiger Lake, Amber Lake, Kaby Lake, Coffee Lake, Whiskey Lake, Comet Lake & Rocket Lake CPU families. Intel will release a microcode update for affected products.
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 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".
Those chips altogether — CPUs, ... Intel's revenue for the upcoming quarter is expected to fall more than 10% year over year to $13.8 billion, per Bloomberg consensus estimates, and earnings per ...
Intel promised microcode updates to resolve the vulnerability. [1] The microcode patches have been shown to significantly reduce the performance of some heavily-vectorized loads. [7] Patches to mitigate the effects of the vulnerability have also been created as part of the forthcoming version 6.5 release of the Linux kernel. [8]
And this weekend, rumors continue to build that Trump's team may be arranging a buyout of Intel (Nasdaq: INTC) that could be funded by Elon Musk. Leaks of the rumor sent Intel up 9.25% in trading ...
Intel incorporated fixes in its processors starting shortly before the public announcement of the vulnerabilities. [ 1 ] On 14 May 2019, a mitigation was released for the Linux kernel , [ 18 ] and Apple , Google , Microsoft , and Amazon released emergency patches for their products to mitigate ZombieLoad.
