We have discovered that it is possible to disclose portions of uninitialized kernel stack memory to user-mode applications in Windows 10 indirectly through the win32k!NtUserPaintMenuBar system call, or more specifically, through the user32!fnINLPUAHDRAWMENUITEM user-mode callback (#107 on Windows 10 1607 32-bit).
In our tests, the callback is invoked under the following stack trace:

The layout of the i/o structure passed down to the user-mode callback that we're seeing is as follows:
--- cut ---

Where 00 denote bytes which are properly initialized, while ff indicate uninitialized values copied back to user-mode. As shown above, there are 20 bytes leaked at offsets 0x6c-0x7f. We have determined that these bytes originally come from a smaller structure of size 0x74, allocated in the stack frame of the win32kfull!xxxSendMenuDrawItemMessage function.
We can easily demonstrate the vulnerability with a kernel debugger (WinDbg), by setting a breakpoint at win32kfull!xxxSendMenuDrawItemMessage, filling the local structure with a marker 0x41 ('A') byte after stepping through the function prologue, and then observing that these bytes indeed survived any kind of initialization and are printed out by the attached proof-of-concept program:

Then, the relevant part of the PoC output should be similar to the following:

The 20 aforementioned bytes are clearly leaked to ring-3 in an unmodified, uninitialized form. If we don't manually insert markers into the kernel stack, an example output of the PoC can be as follows:
--- cut ---

Starting at offset 0x6C, we can observe leaked contents of a kernel _EH3_EXCEPTION_REGISTRATION structure:
.Next = 0x81abd328
.ExceptionHandler = 0x9b20aa80
.ScopeTable = 0xaffb2633
.TryLevel = 0xfffffffe
This immediately discloses the address of the kernel-mode stack and the win32k image in memory -- information that is largely useful for local attackers seeking to defeat the kASLR exploit mitigation, or disclose other sensitive data stored in the kernel address space.
