Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - x86/kvm: Force legacy PCI hole to UC when overriding MTRRs for TDX/SNP When running as an SNP or TDX guest     under KVM, force the legacy PCI hole, i.e. memory between Top of Lower Usable DRAM and 4GiB, to be mapped     as UC via a forced variable MTRR range. In most KVM-based setups, legacy devices such as the HPET and TPM     are enumerated via ACPI. ACPI enumeration includes a Memory32Fixed entry, and optionally a SystemMemory     descriptor for an OperationRegion, e.g. if the device needs to be accessed via a Control Method. If a     SystemMemory entry is present, then the kernel's ACPI driver will auto-ioremap the region so that it can     be accessed at will. However, the ACPI spec doesn't provide a way to enumerate the memory type of     SystemMemory regions, i.e. there's no way to tell software that a region must be mapped as UC vs. WB, etc.
    As a result, Linux's ACPI driver always maps SystemMemory regions using ioremap_cache(), i.e. as WB on     x86. The dedicated device drivers however, e.g. the HPET driver and TPM driver, want to map their     associated memory as UC or WC, as accessing PCI devices using WB is unsupported. On bare metal and non-     CoCO, the conflicting requirements work as firmware configures the PCI hole (and other device memory) to     be UC in the MTRRs. So even though the ACPI mappings request WB, they are forced to UC- in the kernel's     tracking due to the kernel properly handling the MTRR overrides, and thus are compatible with the drivers'     requested WC/UC-. With force WB MTRRs on SNP and TDX guests, the ACPI mappings get their requested WB if     the ACPI mappings are established before the dedicated driver code attempts to initialize the device. E.g.
    if acpi_init() runs before the corresponding device driver is probed, ACPI's WB mapping will win, and     result in the driver's ioremap() failing because the existing WB mapping isn't compatible with the     requested WC/UC-. E.g. when a TPM is emulated by the hypervisor (ignoring the security implications of     relying on what is allegedly an untrusted entity to store measurements), the TPM driver will request UC     and fail: [ 1.730459] ioremap error for 0xfed40000-0xfed45000, requested 0x2, got 0x0 [ 1.732780] tpm_tis     MSFT0101:00: probe with driver tpm_tis failed with error -12 Note, the '0x2' and '0x0' values refer to     enum page_cache_mode, not x86's memtypes (which frustratingly are an almost pure inversion; 2 == WB, 0     == UC). E.g. tracing mapping requests for TPM TIS yields: Mapping TPM TIS with req_type = 0 WARNING: CPU:
