Millions of laptop owners are at risk. Serious vulnerabilities discovered in a huge number of Lenovo PCs
ESET researchers have identified and analyzed three vulnerabilities affecting various models of Lenovo laptops.
The first two – CVE-2021-3971, CVE-2021-3972 – affect UEFI firmware drivers, originally intended for use only in Lenovo’s consumer laptop manufacturing process. Unfortunately, they were erroneously included in production BIOS images without proper deactivation.
An attacker can enable these firmware drivers to directly disable SPI flash protection or the UEFI secure boot feature from a privileged user mode process.
The third vulnerability, CVE-2021-3970, allows arbitrary reads/writes from/to SMRAM, which could lead to malicious code executing with SMM privileges and potentially lead to the deployment of an SPI flash implant.
The problem is that the vulnerabilities affect more than a hundred different models of Lenovo laptops. Given the company’s sales, we are talking about millions of laptops in the hands of users.
ESET specialists reported about the vulnerabilities of Lenovo itself back in October. At the same time, some models will not receive any patches, because their support period has expired. For example, these are Ideapad 330-15IGM and Ideapad 110-15IGR.

First laptop with sub-flagship Intel graphics. Machenike Discovery Edition 2022 received Arc A730M
Intel video cards are still practically unavailable on the market, but sooner or later this will change. So, from today, the Machenike Discovery Edition 2022 laptop with a mid-budget Intel 3D card is available for pre-order.
The laptop is equipped with Arc A730M, which configuration includes 3072 cores and 12 GB of memory. Only the Arc A750M is older.
The laptop is also equipped with a 16-inch 2.5K screen with a frame rate of 165 Hz, a Core i7-12700H processor, 16 GB of RAM and an 80 Wh battery.
The laptop is asking for about $1,275, but a promotion is expected on June 6, during which the price will drop to $1,110. At the same time, there is no information about the date of delivery, so, perhaps, such a laptop will arrive to its customers only in two or three months.
