CVE-2025-47735 Details
Description
inner::drop in inner.rs in the wgp crate through 0.2.0 for Rust lacks drop_slow thread synchronization.
A vulnerability exists in the wgp crate for Rust, specifically in version 0.2.0, due to improper thread synchronization in the drop function of the Inner structure. The issue arises because the drop_slow function, responsible for managing reference counts, lacks adequate synchronization to ensure that only one thread can safely drop a reference at a time. This flaw could lead to unsound behavior in memory management, potentially allowing for use-after-free errors or other concurrency-related issues.
Users can manually adjust the drop logic to include proper synchronization, ensuring that reference counts are managed safely across threads. The wgp crate should be updated to a version that addresses this vulnerability once available.
