CVE-2021-47660 Details
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.
A vulnerability in the Linux kernel's NTFS3 file system implementation has been addressed, which involved memory leaks occurring during error handling in the 'log_replay()' function. The issue arose because all error paths led to a common 'out' point where resources were properly freed, except for this particular path, causing leaks of several resources including 'log', 'ra', and 'log->one_page_buf'.
