Description

A resource leak was found in the TTM (Translation Table Manager) memory management subsystem of the Linux kernel's DRM (Direct Rendering Manager). When moving a buffer object to system memory for swapout fails, the allocated resource is not properly freed, leading to gradual memory exhaustion on systems with active GPU workloads.

Statement

This bug requires graphics hardware using TTM-based drivers (AMD, VMware, etc.) and sustained GPU memory pressure to trigger swap operations. Impact is limited to gradual resource exhaustion under specific workloads.
