Ubuntu: nearly half of users are vulnerable to new cyberthreat

Recent research shows that nearly 40% of Ubuntu operating system users are subject to new, serious cyber threats. These new vulnerabilities, in fact, allow the elevation of privileges within the system, jeopardizing the security of data and operations of its users.

The insidious discovery of security researchers

Security researchers have identified two particularly disturbing vulnerabilities, both related to the handling of the Ubuntu kernel. Referred to as CVE-2021-3493 and CVE-2021-3492, these flaws lead to the possibility of arbitrary code execution in the kernel, as well as privilege escalation for cyberattacks.

The answer from the Ubuntu developers

The Ubuntu development teams, aware of the serious implications of these vulnerabilities, responded quickly by releasing security updates. These patches should act directly on the identified flaws, correcting them to prevent future abuses. However, there has been some resistance in users implementing the update.

The importance of keeping computer systems up to date

To stay safe from these threats, it is imperative that all Ubuntu users immediately install any released security updates. Despite resistance from some, safety should always be the top priority. We remind you that keeping your computer systems constantly updated is the first step in ensuring effective protection from potential attacks.
