Microsoft has pushed fixes for 112 common vulnerabilities and exposures (CVEs) on the first Patch Tuesday of 2026, among them a number of zero-day flaws that were either publicly disclosed or actively exploited prior to patching, and no fewer than eight critical bugs. Although this is a sharp increase in comparison to recent Patch Tuesdays – December 2025 saw Microsoft patch just 56 flaws – it is important to note that the festive season is frequently a quieter time for patches, sometimes by design, and January often brings an uptick in disclosures.
