Discovered by security experts a few years ago Specter and Meltdown Malware, named Malware, had plagued the company by putting the data of millions of Intel users at risk. But now both Intel as well as armThe Specter type is a new security bug faced with.
There are a number of vulnerabilities that manage to infiltrate the processor to run the disallowed code sequence as a security measure. In its latest report, VUSec, the research group collaborating with Intel, Intel 12th Gen (Alder Lake) and affecting ARM processors Specter vulnerability revealed.
AMD prepares to trip Intel: New processors on the way
AMD, which is one step away from the competition with Intel’s 12th generation processors, will close the gap with new processors.
What is the Specter vulnerability affecting Intel and Arm?
This vulnerability, reported by VUSec, targets a number of processors using the ARM architecture with the latest generation Intel chips. Therefore Specter-type threathas the potential to endanger millions of computer and mobile users.
When it was first discovered by researchers Specter-BHB BHI stands for Branch History Injection. According to the researchers’ report, Intel CPUs with BHI have a way of infiltrating core memory. proof of concept gap exists.
Researchers at Vrije University Amsterdam have shared the exploit that allows for random data extraction from the processor’s core memory. danger, as well exploit (the program used to expose the vulnerabilities) as well as root access password It was deciphered with the password loaded from the file.
In addition to leaking data from different privilege levels, the vulnerability can also be exploited for attack through the kernel. For example, using a user-downloaded EBPF program (network traffic technology) or Specter-gadget The contents of the kernel memory can be changed with the help of
Which processors does the Specter-BHB (BHI) vulnerability threaten?
The security report says that all Intel processors released as of 2013 may be affected by this danger. Moreover 13th Generation Raptor Lake and 14th Generation Meteor Lake It is also at risk as it is in the production phase.
on the ARM side Cortex A15, A57, A72 and Neoverse V1, N1 and N2 There is danger to the cores. However, because they are special design apple and Qualcomm It is unknown whether their chips are affected by Specter. In the first tests AMD processors not believed to be at risk.
That’s why both Intel and ARM update for vulnerability It has to publish it, but there was no explanation from the companies on what to do about the vulnerability.
