Three new vulnerabilities were discovered in Intel processors 
Intel representatives recommended updating the BIOS firmware to protect against three new vulnerabilities. This is reported by the Bleeping Computer edition.
A couple of dangerous vulnerabilities appear under the names CVE-2021-0157 and CVE-2021-0158 and have a rating of 8.2 points according to the CVSSv3 standard. With their help, attackers can gain a high level of privileges on the device, which can lead to equipment compromise. The first vulnerability found is related to the distribution of control threads, the second – to an error during input validation.
According to Intel's statement, the vulnerabilities apply to processors of the Xeon E, Xeon W, Celereon N, Pentium Silver, Core 7, 10 families and 11 generations, as well as other lines. The company advised to fix the vulnerabilities with a BIOS update.
The third vulnerability, CVE-2021-0146, is associated with cars equipped with Intel processors. It allows you to gain a high level of privileges during the debugging process.
Despite the high level of severity, the vulnerability can only be exploited through direct contact with the processor. However, hackers can hack into devices locally and then control the hardware remotely.
At the end of the summer, security experts uncovered a new way to hack AMD processors. Hacking is based on forced data exchange between microarchitectural elements of chips.
