A vulnerability in the Linux kernel's KVM x86 implementation related to the per-vCPU MMIO cache has been resolved. The issue involved improper use of memslots in System Management Mode (SMM) address space, which could cause stale cache entries to remain valid after switching address spaces. This could lead to incorrect MMIO exits and bypass of KVM's write-tracking, potentially causing inconsistent nested EPT table states. The fix ensures the use of active memslots for caching and validation, preventing stale entries across address spaces.
