ibm common cryptographic architecture UPGRADE

Affected: >= 7.0.0 and < 7.5.52

Fixed in: 7.5.52

Safe to downgrade to: a release before 7.0.0

1. Check installed version

apt-cache policy common-cryptographic-architecture || rpm -q common-cryptographic-architecture || common-cryptographic-architecture --version

2. UPGRADE to 7.5.52 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade common-cryptographic-architecture

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade common-cryptographic-architecture

Note

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

3. If no update is available yet, DOWNGRADE to a release before 7.0.0 (Debian / Ubuntu)

apt-cache madison common-cryptographic-architecture sudo apt install common-cryptographic-architecture=<VERSION_BEFORE_7.0.0> sudo apt-mark hold common-cryptographic-architecture

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list common-cryptographic-architecture sudo dnf downgrade common-cryptographic-architecture-<VERSION_BEFORE_7.0.0> sudo dnf versionlock add common-cryptographic-architecture

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.
