Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> cachefiles: unmark inode in use in error path<br /> <br /> Unmark inode in use if error encountered. If the in-use flag leakage<br /> occurs in cachefiles_open_file(), Cachefiles will complain "Inode<br /> already in use" when later another cookie with the same index key is<br /> looked up.<br /> <br /> If the in-use flag leakage occurs in cachefiles_create_tmpfile(), though<br /> the "Inode already in use" warning won&amp;#39;t be triggered, fix the leakage<br /> anyway.
