A Record-Breaking Patch Tuesday for June 2026
The release includes 38 critical flaws and one actively exploited zero-day in Microsoft Defender, researchers said.
- Microsoft set a record on Tuesday with its June Patch Tuesday release, addressing 206 CVEs across its products, with 38 deemed critical and the rest important.
- The total number of CVEs shipped by Microsoft this year already exceeds the amount shipped in all of 2018; Redmond addressed 137 vulnerabilities last month, reflecting an ongoing upward trend.

- Microsoft designated 15 of the addressed vulnerabilities as 'more likely' to be exploited, though none are currently under attack in the wild, according to the company.
- Researcher Nightmare Eclipse promised a 'bone shattering' release on June 14, following proof-of-concept disclosures, while experts question how many patches involved AI-assisted coding.
