Microsoft Patches 0-Days Disclosed by Researcher 'Nightmare Eclipse' Amid Heated Rivalry

Ars Technica·medium signal

Microsoft shipped fixes for a zero-day publicly disclosed by researcher Nightmare Eclipse, with a second disclosed zero-day also appearing to be patched, against the backdrop of an unusually adversarial researcher-vendor relationship. The episode underscores ongoing friction in coordinated disclosure when researchers go public before fixes land. A reminder for builders to track disclosure-driven patch cycles on platform dependencies.
