CVE-2020-36463 — Vulnerability in multiqueue — CVE Details

HIGH

Queues allow non-Send types to be sent to other threads, allowing data races

Published December 25, 2020Updated November 8, 2023Source: osv

Summary

Affected versions of this crate unconditionally implemented `Send` for types used in queue implementations (`InnerSend<RW, T>`, `InnerRecv<RW, T>`, `FutInnerSend<RW, T>`, `FutInnerRecv<RW, T>`). This allows users to send non-Send types to other threads, which can lead to data race bugs or other undefined behavior.
