Description Vipul Nair 2026-04-25 11:50:20 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Comment 1 Fabio Valentini 2026-05-11 23:54:55 UTC
I have addressed this to the degree I can.
Updates for the "openssl" crate that fix this issue (and two more CVEs that no bugs have been filed yet):
https://bodhi.fedoraproject.org/updates/?search=rust-openssl-0.10.79

However, there's two groups of packages that have, effectively, opted-out of being covered by rebuilds for security issues in Rust crates.

1) Packages not co-maintained by the Rust SIG:

- aw-server-rust
- awatcher
- clevis-pin-tpm2
- clevis-pin-trustee
- envision
- fido-device-onboard
- keyring-ima-signer
- krun-awsnitro-eif-ctl
- python-cryptography
- s390utils
- trustee
- trustee-guest-components
- virt-firmware-rs

2) Packages that vendor their Rust dependencies:

- 389-ds-base
- arapuca
- bcvk
- bootc
- bpfman
- chunkah
- cosmic-settings-daemon
- fractal
- goose
- rpm-ostree
- rust-bootupd
- rust-zincati
- trunk
- vaultwarden

Maintainers of these packages will need to check whether they're affected (and rebuild, if necessary) themselves.
