Intel has just announced a slew of hardware patches it terms as high security. These could allow different endpoints like workstations, data servers, and mobile devices along with storage products to become seriously compromised. These products include 10th Generation Intel Core Processors as well as Intel Core X-series Processors. Users should take notice of this and upgrade their firmware.
Intel recommends that the users of these affected processors should immediately upgrade to the latest versions so that issues can be addressed. However, these bugs were not the only thing that Intel announced. There is a potential vulnerability in the processors of Intel that could indicate information disclosure, Intel dubbed this as “low severity”.
According to Intel, behavioural discrepancies in some of its processors could potentially allow an authorised user to permit information disclosure through local access. According to Intel, this bug has the capability of infecting and affecting all families of processors that bear the Intel name.
It is recommended by Intel that any product that faces this impact should make use of the LFENCE instruction “after loads that should observe writes from a different thread into the same memory address that is shared”.
In today’s world, firewalls are not enough. And it is important to note that it is not only Intel that has vulnerabilities in hardware security. AMD was host to a successful attack by academic researchers to work around and gain access to AMD’s much-touted Secure Encrypted Visualisation (SEV) tech.
