pqc_kyber is unmaintained

Published Sep 17, 2026 · Updated Sep 18, 2026 · Assigned by RUSTSEC

Description

The crate has had no releases since 0.7.1 (2023-08-23), and the upstream
repository shows no maintainer activity. Open pull requests, including a fix for
a chosen-ciphertext key-recovery flaw in the AVX2 backend
(Argyle-Software/kyber#121), have gone unanswered.
