    "summary": "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.",
