CVE-2024-47727

CVE-2024-47727 is a Linux kernel issue (x86/tdx) where userspace could trick the kernel into performing MMIO via #VE by pointing a syscall at an MMIO address. The root cause was the in-kernel MMIO check in handle_mmio() not guaranteeing the target MMIO address was within the kernel before decodin...
