A critical flaw put millions of computers at risk. Weak security was found in the BIOS code which could allow a hacker to gain access to sensitive information like passwords and encryption keys, potentially gaining control of the system. The bug has been fixed by Intel but it is unclear how many laptops were affected or if others can still be compromised.
The “lenovo security concerns 2021 reddit” is a headline that was released on Reddit in early January. The article talks about the many flaws in the BIOS of Lenovo laptops.

- Security experts have discovered a hole in computer hardware that might enable hackers to get unauthorized access to your computer, infect it with malware, and even steal your personal information.
- The BIOS (Basic Input Output System) firmware, which prepares your computer for booting, has several faults.
- Hackers will be able to take control of your PC due to a critical BIOS security weakness that allows firmware authentication to be bypassed.
The announcement that there is an imminent BIOS vulnerability will annoy Windows users who use Lenovo, Intel, and other PCs.
Firmware protection company Binarly uncovered the weaknesses, which may be used to take complete administrative control of a target machine.
More than two dozen hardware manufacturers, including top-end OEMs such as Intel, AMD, and Lenovo, are said to be impacted, according to the business.
Flaws with a high effect
The basic layer for all current PCs is UEFI, which stands for Unified Extensible Firmware Interface.
It provides a standardized method for devices to communicate with one another, including through a network. It also enables administrators to control the settings of numerous devices such as printers, cameras, and other similar devices.
With this comprehensive tutorial, you can simply resolve any BIOS difficulties, particularly at startup.
Insyde’s UEFI firmware is vulnerable to 23 flaws that would allow attackers to gain full control of the computer while maintaining remote access. These vulnerabilities are categorized as critical and Flaws with a high effect.
There are twenty-three serious faults.
Malicious actors might get access to the endpoint in a variety of methods, including keylogging attacks, a system information leak, or complete physical access, thanks to 23 vulnerabilities that have been classed as severe or high severity.
CVE-2020-27339, CVE-2020-5953, CVE-2021-33625, CVE-2021-33626, CVE-2021-33627, CVE-2021-41837, CVE-2021-41838, CVE-2021-41839, CVE-2021-41840, CVE-2021-41841, CVE-2021-42059, CVE-2021-42060, CVE-2021-42060, CVE-2021-42113, CVE-
These three are rated 9.8 out of 10 and are considered high-impact. CVE-2021-45969, CVE-2021-45970, and CVE-2021-45971 are all CVE-2021-45969, CVE-2021-45970, and CVE-2021-45971 vulnerabilities.
The source of the issue was discovered in the InsydeH2O firmware framework code’s reference code. The Insyde-based firmware SDK was used by all of the aforementioned suppliers (over 25) to produce their (UEFI) firmware.
Patches to fix the problem
Insyde security experts have uncovered an exceedingly critical security hole in the firmware of certain Intel CPUs.
Security fixes are beneficial, but they aren’t always made available in a timely manner. To assist fix the problem, Insyde supplied firmware updates, however they must now be approved by OEMs and put onto impacted devices, which might take some time.
To put it another way, you could receive a patch for your computer today, but it won’t function until tomorrow. Furthermore, if you do not also apply a patch for another piece of software that you use on a regular basis, your PC may become unworkable after you install it.
Some OEMs have yet to confirm that they have been impacted, therefore it will take some time. If you haven’t done so before, you can simply upgrade your BIOS.
