+  "details": "An issue was identified in the `VmFd::create_device function`, leading to undefined behavior and miscompilations on rustc 1.82.0 and newer due to the function's violation of Rust's pointer safety rules.\n\nThe function downcasted a mutable reference to its `struct kvm_create_device` argument to an immutable pointer, and then proceeded to pass this pointer to a mutating system call. Rustc 1.82.0 and newer elides subsequent reads of this structure's fields, meaning code will not see the value written by the kernel into the `fd` member. Instead, the code will observe the value that this field was initialized to prior to calling `VmFd::create_device` (usually, 0).\n\nThe issue started in kvm-ioctls 0.1.0 and was fixed in 0.19.1 by correctly using\na mutable pointer.\n",
