Microsoft Patches High-Severity Zero-Days After Researcher Dispute

Microsoft releases fixes for two critical vulnerabilities disclosed by an independent researcher.

Microsoft has released patches for two high-severity zero-day vulnerabilities. The fixes come after a tense public dispute with a security researcher known as "Nightmare Eclipse," who disclosed the flaws and provided proof-of-concept code.

The conflict reportedly began after Microsoft reneged on a prior agreement with the researcher, leading to the public disclosure of these vulnerabilities before they were patched.
