2 Processor MMIO Stale Data Vulnerabilities
5 Processor MMIO Stale Data Vulnerabilities are a class of memory-mapped I/O
6 (MMIO) vulnerabilities that can expose data. The sequences of operations for
8 vulnerabilities require the attacker to have access to MMIO, many environments
9 are not affected. System environments using virtualization where MMIO access is
22 one microarchitectural buffer or register to another. Processor MMIO Stale Data
49 processors, MMIO primary reads will return 64 bytes of data to the core fill
57 Some endpoint MMIO registers incorrectly handle writes that are smaller than
117 specific variants of Processor MMIO Stale Data vulnerabilities and mitigation
145 is more critical, or the untrusted software has no MMIO access). Note that
152 Like MDS, all variants of Processor MMIO Stale Data vulnerabilities  have the
169 with MMIO capability. Therefore, VERW is not required for kernel/userspace. For
170 virtualization case, VERW is only needed at VMENTER for a guest with MMIO
189 execute VERW at VMENTER only for MMIO capable guests. On CPUs not affected by
190 MDS/TAA, guest without MMIO access cannot extract secrets using Processor MMIO
195 The kernel command line allows to control the Processor MMIO Stale Data
