A critical vulnerability (CVE-2025-69784) was discovered in OpenEDR 2.5.1.0, where a local, non-privileged attacker can abuse a vulnerable IOCTL interface exposed by the kernel driver to modify the DLL injection path. This allows the attacker to cause OpenEDR to load an attacker-controlled DLL into high-privilege processes, resulting in arbitrary code execution with SYSTEM privileges and full system compromise. This highlights the risk posed by insecure kernel drivers—even from security vendors.

Stealthy and can inject into a running process without creating a new thread, which is a common detection heuristic. This allows the attacker to cause OpenEDR to

The result: The DLL sits in memory with no LDR entry, no file on disk, and no LoadLibrary call. It is invisible to most monitoring tools.

A Kernel DLL Injector is a type of software tool used to inject Dynamic Link Libraries (DLLs) into the address space of a process running in kernel mode. This technique is often employed by system administrators, developers, and security researchers to load custom or proprietary DLLs into the kernel for various purposes, such as debugging, testing, or enforcing specific security policies.
