Avi Kivity ac1b714e78 KVM: MMU: Fix guest writes to nonpae pde ... KVM shadow page tables are always in pae mode, regardless of the guest setting. This means that a guest pde (mapping 4MB of memory) is mapped to two shadow pdes (mapping 2MB each). When the guest writes to a pte or pde, we intercept the write and emulate it. We also remove any shadowed mappings corresponding to the write. Since the mmu did not account for the doubling in the number of pdes, it removed the wrong entry, resulting in a mismatch between shadow page tables and guest page tables, followed shortly by guest memory corruption. This patch fixes the problem by detecting the special case of writing to a non-pae pde and adjusting the address and number of shadow pdes zapped accordingly.
