Memory Management Issue in Linux Kernel Affects Graphics Processing Units

CVE-2026-46224

What is CVE-2026-46224?

A memory management vulnerability exists in the Linux kernel, particularly affecting the Direct Rendering Manager (DRM) related to the allocation of graphics memory buffers. When the function drm_gpuvm_resv_object_alloc() encounters an error, it fails to free pre-allocated buffer storage, leading to potential memory leaks. The function xe_dma_buf_init_obj() needs to handle its error paths correctly by releasing the storage buffer when an allocation fails. This ensures that resources are managed properly and prevents complications during buffer import processes.
