Routine

MEDIUM 5.6UPGRADE

CVE-2025-52638 is a medium-severity flaw (CVSS 5.6) affecting aion. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

HCL AION is affected by a vulnerability where generated containers may execute binaries with root-level privileges. Running containers with root privileges may increase the potential security risk, as it grants elevated permissions within the container environment. Aligning container configurations with security best practices requires minimizing privileges and avoiding root-level execution wherever possible.

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.

hcl aion UPGRADE

Affected: >= 2.0 and < 2.1.2

Fixed in: 2.1.2

Safe to downgrade to: a release before 2.0

1. Check installed version

apt-cache policy aion || rpm -q aion || aion --version

2. UPGRADE to 2.1.2 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade aion

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade aion

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 2.0 (Debian / Ubuntu)

apt-cache madison aion sudo apt install aion=<VERSION_BEFORE_2.0> sudo apt-mark hold aion

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

dnf --showduplicates list aion sudo dnf downgrade aion-<VERSION_BEFORE_2.0> sudo dnf versionlock add aion

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.
