Like the Spectre and Meltdown vulnerabilities first disclosed in early 2018, the new batch takes advantage of side-channel vulnerabilities in the way Intel processors attempt to predict the next instruction they will have to execute. Any available updates will be listed here - click Update to apply them.
What makes the exploits especially unsafe is that they allow hackers to bypass the virtual barriers separating the different programs on a computer. In the case of these new bugs, updating everything is the best thing you can do right now.
SECURITY TYPES have uncovered a series of vulnerabilities in Intel processors that could, in theory, allow hackers to steal data recently accessed by the CPU.
No one knows if the bugs have been exploited by real attackers in the real world. Note, AMD and ARM chips are not affected by the bug. Meltdown and Spectre ended up causing a lot of disruption - and badly damaged Intel's reputation. A new threefold of attacks are different from and more risky than Meltdown, Spectre and their variations because they can leak data from CPU buffers, which is not necessarily present in caches.
The exploit could as easily read secure tokens or other passwords.

Software fixed for the Zombieload bug are available for computers running Windows, MacOS, and Linux. In this way, researchers can read what is now being done on the computer in plain text. What we hope to do in this article is to give you a high-level overview of what went wrong and then offer guidance on what exactly the new vulnerabilities mean for you. Referred to as Microarchitectural Data Sampling by Intel, the vulnerability has also been called ZombieLoad, Fallout, and Rogue In-Flight Data Load by the security researcher groups that discovered it.
As explained by TechCrunch's Zack Whittaker, ZombieLoad allows hackers to "exploit design flaws, rather than inject malicious code". A year ago two major leaks in processors were discovered: called Spectre and Meltdown.
It said most patched devices would lose up to a 3 per cent in performance.
According to the research paper, disabling hyperthreading might be the only way to completely prevent being at risk of a Zombieload attack. Ultimately, none of that matters in the face of these attacks. While Intel rates the attacks as "low to medium" in severity, researchers from the institutions that discovered the attacks told Wired that they could "reliably dig through that raw output to find the valuable information they sought". "We hear anything that these components exchange". As with Meltdown and Spectre, the mitigations will generally not hurt performance too much on home PCs, but some datacenter workloads could see performance drop by 8-9 percent.
