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. Stack-based buffer overflow vulnerabilities can result in severe impacts, such as data corruption, system crashes, and arbitrary code execution. Buffer over-reads, on the other hand, can be weaponized to read out-of-bounds memory, leading to the exposure of secret data. 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.
