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.
