GHSA-j8cj-hw74-64jv: Hive has Double-free and Use After Free Vulnerabilities

February 28, 2026

Drop implementation for Hive did perform free, but so did Hive::close, which, at the end of the scope performed Drop, therefore triggering double-free.

Additionally, function Hive::from_handle was not marked as unsafe, making it, in combination with as_handle easy to clone and trigger double-free in safe code or triggering UB when using invalid pointer.
