A local attacker in a SEV guest VM\ncould possibly use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2023-46813)\n\nIt was discovered that the io_uring subsystem in the Linux kernel contained\na race condition, leading to a null pointer dereference vulnerability.
