**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue concerns the Linux kernel, specifically the drm/amdgpu component. It involves avoiding the use of a null object of the framebuffer. Instead of directly using `state->fb->obj[0]`, the object is obtained from the framebuffer by calling `drm gem fb get obj()`, and an error code is returned when the object is null. This prevents the use of a null framebuffer object. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
