hidglobal safe UPGRADE

Affected: >= 5.8.0 and <= 5.11.3

Fixed in: newer than 5.11.3

Safe to downgrade to: a release before 5.8.0

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

dnf --showduplicates list safe sudo dnf downgrade safe-<VERSION_BEFORE_5.8.0> sudo dnf versionlock add safe

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
