X-Git-Tag: v2.6.19-rc1~889 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=52149ba6b0ddf3e9d965257cc0513193650b3ea8;p=pandora-kernel.git [S390] user readable uninitialised kernel memory. 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.
