With Microsoft's broken Meltdown mitigation in place, apps and users could now read and write kernel memory, granting total control over the system.
This was due to Redmond's engineers accidentally marking the page tables, which describe the computer's memory layout, as readable-writable for usermode programs, allowing normal applications to rejig memory mappings as necessary to freely access kernel virtual memory.
