[Bug 1866254] CVE-2011-0463 kernel: ocfs2_prepare_page_for_write function does not properly handle holes that cross page boundaries leads to information exposure

The ocfs2_prepare_page_for_write function in fs/ocfs2/aops.c in the Oracle Cluster File System 2 (OCFS2) subsystem in the Linux kernel does not properly handle holes that cross page boundaries, which allows local users to obtain potentially sensitive information from uninitialized disk locations by reading a file.
