Security Researcher Alexander Popov found vulnerabilities in the kernel of Linux operating systems that could allow an attacker to escalate local privileges on a victims network. Popov was able to successfully test an exploit of one of the vulnerabilities on Fedora Server 33, notifying the Linux Foundation, a non-profit consortium designed to standardize support for the open-source Linux system, and other parties through email on February 5. Privilege escalation vulnerabilities are considered dangerous because of the level of control they can give an attacker within a victim network.”]
