2006-09-28	[S390] user readable uninitialised kernel memory.	Martin Schwidefsky	1	-6/+16
	A user space program can read uninitialised kernel memory by appending to a file from a bad address and then reading the result back. The cause is the copy_from_user function that does not clear the remaining bytes of the kernel buffer after it got a fault on the user space address.
