Chaotic Eclipse Released GreenSection, A PoC For NVIDIA Memory Corruption Zero-Day
Researcher Chaotic Eclipse released GreenSection, a PoC exploiting an unpatched out-of-bounds write in NVIDIA Windows user-mode shared memory.
Security researcher Chaotic Eclipse disclosed an out-of-bounds write in NVIDIA's Windows user-mode components, which share a global memory section (\BaseNamedObjects\{52813408-3561-4705-820a-2b3b78be92ba}) with full read/write access to all users. The PoC crashes applications running Vulkan or OpenGL; the researcher says the bug could cross user boundaries or compromise dwm.exe but did not fully assess the impact. No CVE has been assigned and no patch is mentioned. The researcher recently released zero-day PoCs against Kaspersky, Avast, and CrowdStrike Falcon.
- NVIDIA user-mode components share a global memory section with full read/write access
- Reused data from the shared section causes out-of-bounds memory writes
- PoC crashes Vulkan or OpenGL applications; potential to compromise dwm.exe
