Qualcomm Chipsets and Lenovo BIOS Get Security Updates to Fix Multiple Flaws

Reading Time: 2 mins read

Qualcomm on Tuesday released patches to address multiple security flaws in its chipsets, some of which could be exploited to cause information disclosure and memory corruption.

The five vulnerabilities — tracked from CVE-2022-40516 through CVE-2022-40520 — also impact Lenovo ThinkPad X13s laptops, prompting the Chinese PC maker to issue BIOS updates to plug the security holes.

The list of flaws is as follows:

  • CVE-2022-40516, CVE-2022-40517 & CVE-2022-40520 (CVSS scores: 8.4) – Memory corruption in Core due to stack-based buffer overflow
  • CVE-2022-40518 & CVE-2022-40519 (CVSS scores: 6.8) – Information disclosure due to buffer over-read in Core

Successful exploitation of the aforementioned flaws could allow a local adversary with elevated privileges to cause memory corruption or leak sensitive information, Lenovo noted in an alert published Tuesday.

Also remediated by Lenovo are four more buffer over-read vulnerabilities in ThinkPad X13 BIOS that could lead to information disclosure. The flaws are tracked as CVE-2022-4432, CVE-2022-4433, CVE-2022-4434, and CVE-2022-4435.
