CVE-2023-34326

Name of the Vulnerable Software and Affected Versions AMD-Vi (affected versions not specified)

Description The caching invalidation guidelines from the AMD-Vi specification are incorrect on some hardware, leading to devices malfunctioning if some fields of the DTE are updated but the IOMMU TLB is not flushed.
