ibm qradar edr UPGRADE

Affected: >= 3.12.0 and < 3.12.24

Fixed in: 3.12.24

Safe to downgrade to: a release before 3.12.0

1. Check installed version

apt-cache policy qradar-edr || rpm -q qradar-edr || qradar-edr --version

2. UPGRADE to 3.12.24 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade qradar-edr

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade qradar-edr

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 3.12.0 (Debian / Ubuntu)

apt-cache madison qradar-edr sudo apt install qradar-edr=<VERSION_BEFORE_3.12.0> sudo apt-mark hold qradar-edr

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

dnf --showduplicates list qradar-edr sudo dnf downgrade qradar-edr-<VERSION_BEFORE_3.12.0> sudo dnf versionlock add qradar-edr

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.
