Operating Systems left vulnerable due to Intel debug Misunderstanding
Almost all Operating Systems including Microsoft Windows, OSX and Linux have misinterpreted the way a low-level chip instruction works, resulting in a vulnerability which could allow malicious code to access sensitive information or run with higher privileges then intended in the affect operating systems. As a result of the discovery, operating system vendors have this month started pushing updates to fix the identified vulnerabilities.
The discovery was made by security researchers who identified the vulnerability in the way an instruction in Intel and AMD chips was being used by operating system vendors.
This new vulnerability CVE-2018-8897 comes on the back of a wave of new chip architecture vulnerabilities which have been discovered this year after the infamous Spectre and Meltdown vulnerabilities have caused security researches to look at the way low level chip architecture can be abused more closely.
While the impact of these new vulnerabilities has not yet been fully felt, it is vulnerabilities like these that, when left unpatched, allow cyber criminals to compromise companies through online attacks.
