Kernel page-table isolation
Kernel page-table isolation (KPTI or PTI, previously called KAISER) is a Linux kernel feature that mitigates the Meltdown security vulnerability (affecting mainly Intel's x86 CPUs) and improves kernel hardening against attempts to bypass kernel address space layout randomization (KASLR). It works by better isolating user space and kernel space memory. KPTI was merged into Linux kernel version 4.15, and backported to Linux kernels 4.14.11, 4.9.75, and 4.4.110. Windows and macOS released similar updates. KPTI does not address the related Spectre vulnerability.
