1) Untrusted search path (CVE-ID: CVE-2020-0570)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a logic error in BIOS firmware for 8th, 9th and 10th Generation Intel(R) Core(TM) Processor. An attacker with physical access to the system can execute arbitrary code and gain unauthorized access to the system.

This vulnerability was initially reported in QLibrary from Qt for certain x86 machines searches that were performed for certain libraries and plugins relative to current working directory of the application. A local user can place files in the file system and influence the working directory of Qt-based applications to load and execute malicious code. 

Note, this vulnerability does not affect Windows systems.

2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-0571)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to improper conditions check in BIOS firmware for 8th Generation Intel(R) Core(TM) Processors and Intel(R) Pentium(R) Silver Processor Series. A local user can run a specially crafted program to gain access to sensitive information.
