rust-psa-crypto-sys was only ever used by end user app parsec which was retired in F-42 (never shipped GA). It linked against rust-cryptoki 0.6.2 which was shipped in GA, but not linked against later updates. So the rust-psa-crypto-sys is still vulnerable but it's unused in rust binaries and is deprecated in Fedora (and dead upstream).
