In the Linux kernel, the following vulnerability has been resolved:
fs/proc/task_mmu: move mmu notification mechanism inside mm lock Move mmu
notification mechanism inside mm lock to prevent race condition in other
components which depend on it. The notifier will invalidate memory range.
Depending upon the number of iterations, different memory ranges would be
invalidated. The following warning would be removed by this patch: WARNING:
CPU: 0 PID: 5067 at arch/x86/kvm/…/…/…/virt/kvm/kvm_main.c:734
kvm_mmu_notifier_change_pte+0x860/0x960
arch/x86/kvm/…/…/…/virt/kvm/kvm_main.c:734 There is no behavioural and
performance change with this patch when there is no component registered
with the mmu notifier. [[email protected]: narrow the scope of
`range’, per Sean]
