Vulnerability from github – Published: 2025-03-18 21:31 – Updated: 2025-03-18 21:31

Details

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.

Severity

5.5 (Medium)
