Microsoft has released its Patch Tuesday updates for May 2026, fixing a total of 137 flaws, including nine critical ones. This marks the first time in two years that there are no zero-day vulnerabilities. However, administrators still have a significant amount of work to do to ensure their systems are secure.
What Happened
In addition to Microsoft's Patch Tuesday updates, Signal has introduced new in-app confirmations and warning messages to protect users from phishing and social engineering attempts. The new features aim to introduce enough friction to give users time to evaluate the safety of external requests.
