WS-2022-0155
Date: August 19, 2025
In arrow2 in Rust, the struct Ffi_ArrowArray implements #derive(Clone) that is inconsistent with its custom implementation of Drop, resulting in a double free when cloned. Cloning this struct in safe results in a segmentation fault, which is unsound. Versions 0.7.1, 0.8.2 and 0.9.2 contain a patch for this issue.
