NightmareEclipse Releases PoCs for Avast, Kaspersky, and NVIDIA Flaws

NightmareEclipse published three proof-of-concept vulnerability disclosures—PrettyPrague (an Avast sandbox privilege-escalation PoC claiming SYSTEM/SAM access), HardBreacher (an unstable Kaspersky Endpoint Security PoC attempting to place a library into System32), and GreenSection (an NVIDIA shared-memory flaw causing out-of-bounds writes and crashes). None of the findings have CVEs or vendor confirmation, impacts range from local crashes to claimed reliable SYSTEM escalation, and organizations are advised to restrict unknown program execution and monitor vendor bulletins.
