Object Leak in Linux Kernel Affecting DRM/MSM Components

CVE-2025-40069

What is CVE-2025-40069?

A vulnerability has been identified in the Linux kernel, particularly affecting the DRM (Direct Rendering Manager) and MSM (Mobile Station Modem) components. This issue arises from an object reference leak during the handle lookup process. In scenarios where the lookup fails midway, there can be an accumulation of unyielded object references, potentially leading to resource exhaustion and negatively affecting system stability. Applying the relevant patches is crucial to mitigate this risk and maintain the integrity of the kernel.
