Microsoft just released its first round of Patch Tuesday updates this year and you should update your Windows PC right now to stay safe.

All the three Microsoft Access issues, on the other hand, have been credited to Unpatched.ai, an AI-guided vulnerability discovery platform. Action1 also noted that while the flaws are categorized as remote code execution (RCE) vulnerabilities, exploitation requires an attacker to convince the user to open a specially crafted file.

All three zero-day vulnerabilities have a CVSS score of 7.8 and could allow an attacker to gain system privileges.

Yesterday was January’s big Patch Tuesday, where Microsoft rolled out a big bundle of security updates across several apps and services, eliminating 159 security vulnerabilities. This is the most extensive Patch Tuesday of the last few years with more than double the usual number of fixed security flaws.
