CVE-2025-40181

CVE-2025-40181 : In the Linux kernel x86/kvm, when running as an SNP/TDX guest, forcing the legacy PCI hole to UC by overriding MTRRs can cause ACPI-reported SystemMemory regions mapped as WB to conflict with device memory WC/UC requirements. This can lead to ioremap() failures for PCI devices (e...
