A memory leak vulnerability was identified and fixed in the f2fs_rename() function of the Linux kernel's F2FS filesystem implementation. The issue was caused by a missing call to free allocated filename resources after a rename operation, introduced in a prior commit. This flaw could lead to increased memory usage and potential denial of service. The vulnerability has a medium severity score of 5.5 CVSS v3.1 with an impact on availability only. No affected versions are explicitly stated. No known exploits in the wild have been reported.
