CVE-2025-47735Public exploit

Memory corruption via unsynchronized reference-count deallocation

Published May 9, 2025 · Updated May 9, 2025

Race condition in Nugine wgp 0.2.0 and earlier allows local users to corrupt memory during concurrent object destruction. The InnerPtr::drop path uses a Release-only reference-count decrement followed by a separate Acquire load, so concurrent threads can race into Box deallocation and double-free the same allocation. Exploitation requires a high-complexity local concurrency race; published scoring limits the reported consequence to low-integrity impact without confidentiality or availability impact.
