Linux mremap() TLB Flush Too Late

Linux: mremap TLB flush too late with concurrent ftruncate CVE-2018-18281 Tested on the master branch 4.19.0-rc7+. sysmremap takes current-mm-mmapsem for writing, then calls mremapto-movevma-movepagetables. movepagetables first calls moveptes which takes PTE locks, moves PTEs, and drops PTE locks...

CVE-2017-18202

The oomreaptaskmm function in mm/oomkill.c in the Linux kernel, before 4.14.4, mishandles gather operations. This allows attackers to cause a denial of service TLB entry leak or use-after-free or possibly have unspecified other impact by triggering a copytouser call within a certain time window...

CVE-2017-18202

The CVE-2017-18202 issue affects the Linux kernel prior to 4.14.4, where __oom_reap_task_mm in mm/oom_kill.c mishandles gather operations. This can enable a local attacker to cause a denial of service via a TLB entry leak or use-after-free, potentially with other unspecified impacts by triggering...
