Description:
A vulnerability has been reported in the Linux Kernel, which can be exploited by malicious, local users to gain knowledge of potentially sensitive information.
The vulnerability is caused due to the "copy_from_user" function not correctly clearing kernel buffers after receiving a fault because of invalid user space addresses. This can be exploited to read uninitialised kernel memory by appending to files from invalid addresses.
Note: The vulnerability affects the s390 architecture only.
