CVE-2025-69784: A local, non-privileged attacker can abuse a vulnerable IOCTL interface exposed by the OpenEDR 2.5.1.0 kernel

Routine

HIGH 8.8DOWNGRADE

CVE-2025-69784 is a high-severity flaw (CVSS 8.8) affecting openedr. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A local, non-privileged attacker can abuse a vulnerable IOCTL interface exposed by the OpenEDR 2.5.1.0 kernel driver to modify the DLL injection path used by the product. By redirecting this path to a user-writable location, an attacker can cause OpenEDR to load an attacker-controlled DLL into high-privilege processes. This results in arbitrary code execution with SYSTEM privileges, leading to full compromise of the affected system.

xcitium openedr DOWNGRADE

Affected: 2.5.1.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.5.1.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2.5.1.0 (Debian / Ubuntu)

apt-cache madison openedr sudo apt install openedr=<VERSION_BEFORE_2.5.1.0> sudo apt-mark hold openedr

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list openedr sudo dnf downgrade openedr-<VERSION_BEFORE_2.5.1.0> sudo dnf versionlock add openedr

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.
