In SEV guest VMs, the CPU may fail to flush the Translation Lookaside Buffer (TLB) following a particular sequence of operations that includes creation of a new virtual machine control block (VMCB). The failure to flush the TLB may cause the microcode to use stale TLB translations which may allow for disclosure of SEV guest…
TOCTOU (time-of-check to time-of-use) issue in the System Management Unit (SMU) may result in a DMA (Direct Memory Access) to invalid DRAM address that could result in denial of service. Zafiyet ile ilgili Genel Bilgi, Etki ve Çözümleri için Devamını Oku Kaynak: National Vulnerability Database
Failure to flush the Translation Lookaside Buffer (TLB) of the I/O memory management unit (IOMMU) may lead an IO device to write to memory it should not be able to access, resulting in a potential loss of integrity.
