  "summary": "drm/virtio: release the GEM object on virtio_gpu_vram_create() errors",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/virtio: release the GEM object on virtio_gpu_vram_create() errors\n\nvirtio_gpu_vram_create() frees the object with a bare kfree(vram) on\nboth error paths after drm_gem_private_object_init() has run, and on the\nsecond one after drm_gem_create_mmap_offset() has linked obj->vma_node\ninto the device's VMA offset manager. The freed object stays in that\ninterval tree, so a later lookup or insertion walks freed memory, and\nthe dma_resv and gpuva lock are never destroyed.\n\nCall drm_gem_object_release() before kfree() on both paths.",
