In the Linux kernel, the following vulnerability has been resolved:
drm/xe/dma-buf: fix UAF with retry loop
Retry doesn't work here, since bo will be freed on error, leading to UAF. However, now that we do the alloc & init before the attach, we can now combine this as one unit and have the init do the alloc for us. This should make the retry safe.
