Routine

MEDIUM 5.1UPGRADE

CVE-2026-84290 is a medium-severity flaw (CVSS 5.1) affecting guardium data protection. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

IBM Guardium Data Protection 12.0, 12.1, 12.2 is affected by an improper validation of user-supplied pointers in the WfpMonitor kernel driver. Certain METHOD_NEITHER IOCTL handlers dereference user-controlled pointers without adequate probing and exception handling, potentially allowing a privileged local attacker to cause a system crash or perform limited kernel-memory reads.

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.

ibm guardium data protection UPGRADE

Affected: >= 12.0 and <= 12.2

Fixed in: newer than 12.2

Safe to downgrade to: a release before 12.0

1. Check installed version

apt-cache policy guardium-data-protection || rpm -q guardium-data-protection || guardium-data-protection --version

2. UPGRADE to newer than 12.2 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade guardium-data-protection

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade guardium-data-protection

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 12.0 (Debian / Ubuntu)

apt-cache madison guardium-data-protection sudo apt install guardium-data-protection=<VERSION_BEFORE_12.0> sudo apt-mark hold guardium-data-protection

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

dnf --showduplicates list guardium-data-protection sudo dnf downgrade guardium-data-protection-<VERSION_BEFORE_12.0> sudo dnf versionlock add guardium-data-protection

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.
