In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Fix iommu domain lifetime race during device removal
When force_iova mode is enabled, amdxdna_remove() frees xdna->domain. If
amdxdna_gem_obj_free() is called after device removal, it may attempt to
access xdna->domain, resulting in a use-after-free.
Fix the race by adding freeing xdna->domain as a managed release action,
so its lifetime is managed by DRM and remains valid until all managed
resources are released.
