CVE-2024-47727

In the Linux kernel, the following vulnerability has been resolved: x86/tdx: Fix "in-kernel MMIO" check TDX only supports kernel-initiated MMIO operations. The handlemmio function checks if the VE exception occurred in the kernel and rejects the operation if it did not. However, userspace can...

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...

CVE-2012-3432

The handlemmio function in arch/x86/hvm/io.c in the MMIO operations emulator for Xen 3.3 and 4.x, when running an HVM guest, does not properly reset certain state information between emulation cycles, which allows local guest OS users to cause a denial of service guest OS crash via unspecified...
