Linux Kernel Vulnerability Affecting DRM/AMD Display Components

CVE-2025-38205

What is CVE-2025-38205?

A vulnerability in the Linux kernel's DRM/AMD display interface could lead to a divide by zero condition, affecting the stability of graphical rendering. Specifically, if the dummy values in the populate_dummy_dml_surface_cfg() function are not properly initialized, it may result in erroneous calculations in downstream functions like CalculateVMAndRowBytes(). This flaw emphasizes the importance of initializing variables to prevent unintended behaviors, ensuring the reliability of the display operations within the kernel.
