Intel vulnerable to lvi processors: affects cpu performance
Table of contents:
Intel processors are again protagonists for being vulnerable to LVI. Fixing it would affect its performance. We tell you everything.
It appears that " the blue giant " is being rocked by various vulnerabilities in recent months. This time, it is a vulnerability that could leak sensitive information. The problem is your solution: a lot of performance could be lost. Next, we tell you all the details.
Intel processors vulnerable to LVI
This is a new class of security vulnerabilities that affect Intel processors. These could cause some sensitive information to leak, but this is not the worst news for you Intel users: the solution via software-firmware would cause a significant performance reduction. According to "The Register", "from 2x to 19x", although it would only affect servers.
To fully mitigate these vulnerabilities, Intel would have to redesign its compilers. These are found under the names of CVE-2020-0551 and Intel-SA-00334. It is not a remote execution thread, but multi-host servers are positioned as physical servers that are managed through virtual servers.
According to the researchers, the description of this vulnerability would be as follows:
LVI changes previous data extraction attacks like Meltdown, Foreshadow, RIDL, Fallout and ZombieLoad, and defeats all existing solutions. Instead of filtering the victim's data directly to the attacker, it proceeds in the opposite direction: we "inject" the attacker's data through hidden processor buffers into a victim program and hack the transient execution to obtain confidential information, such as fingerprints. digital or passwords of the victim.
BitDefender anti-virus discovered LVI and shared their study with Intel. We hope that they will fix this issue that makes Intel processors vulnerable soon.
We recommend the best processors on the market
Do you think Intel is having a lot of security problems? Is it the fault of the initial design or do they get a lot of attacks?
