AI-assisted bug discovery is cited as a driver of the increasing patch volume. Notable zero-days include CVE-2026-49160 (IIS denial of service, reported by OpenAI's Codex), CVE-2026-45586 (Windows Collaborative Translation Framework elevation of privilege), and CVE-2026-50507 (BitLocker elevation of privilege), several tied to a prolific researcher known as Nightmare Eclipse who has threatened a larger 'bone shattering' drop in July. A Visual Studio Code zero-day enabling GitHub token theft with a single click was also patched after a researcher published exploitation details. Separately, 72 Microsoft public repositories were infected by a variant of the Shai-Hulud worm targeting the Azure Durable Task SDK. Google patched 429 Chrome vulnerabilities on June 3, and Adobe shipped large update bundles across multiple products. ## Full article daily.dev links to this article rather than hosting it.
