Nightmare Eclipse Drops CrowdStrike, Nvidia, Avast Zero-Day Exploits
Nightmare Eclipse drops three zero-day exploits targeting Avast, CrowdStrike, and Nvidia products.
Security researcher Nightmare Eclipse has released three zero-day exploits targeting Avast, CrowdStrike, and Nvidia. The exploits, named PrettyPrague, FalconFlank, and GreenSection, allow for privilege escalation, potentially granting attackers full system privileges or enabling cross-user compromise. Avast and CrowdStrike have acknowledged the vulnerabilities and are investigating, while Nvidia has not yet responded.

The lesson from this incident
Full lessonSecurity researcher Nightmare Eclipse publicly released three zero-day exploits — PrettyPrague, FalconFlank, and GreenSection — targeting widely deployed security and driver software from Avast, CrowdStrike, and Nvidia. The vulnerabilities enable privilege escalation, meaning attackers could gain full system control or compromise other users on the same machine. This is particularly alarming given that CrowdStrike and Avast are security tools themselves, creating an ironic attack surface within the very software meant to defend systems. Public release of unpatched exploits dramatically shrinks the window organizations have to respond before threat actors weaponize them. The lack of response from Nvidia compounds the risk, leaving users of its drivers without official guidance or remediation.
