CVE-2018-18281

Since Linux kernel version 3.2, the mremap syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate removes entries from the pagetables of a task that is in the middle of mremap, a stale TLB entry can remain for a short time that permits access to a physical pag...
