Comment 1 Debarshi Ray 2026-06-01 21:25:40 UTC

This CVE (ie., CVE-2026-41163) only affects bubblewrap binaries (ie., /usr/bin/bwrap) that have the setuid bit set:
https://github.com/containers/bubblewrap/releases/tag/v0.11.2
https://github.com/containers/bubblewrap/security/advisories/GHSA-xq78-7hw4-5jvp

Fedora has never used those.
