Description
In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix some memory leaks in an error handling path of 'log_replay()' All error handling paths lead to 'out' where many resources are freed. Do it as well here instead of a direct return, otherwise 'log', 'ra' and 'log->one_page_buf' (at least) will leak.
