CVE-2022-49550

CVE-2022-49550 affects the Linux kernel ntfs3 filesystem. The root cause is the absence of the ‘invalidate_folio’ method, which leads to a memory leak where cached written data are not freed after unmount. The documented fix is to add a new implementation, block_invalidate_folio, to ntfs3 to reso...

CVE-2022-49550 fs/ntfs3: provide block_invalidate_folio to fix memory leak

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: provide blockinvalidatefolio to fix memory leak The ntfs3 filesystem lacks the 'invalidatefolio' method and it causes memory leak. If you write to the filesystem and then unmount it, the cached written data are not free...

CVE-2021-47660

CVE-2021-47660 is addressed by a Linux kernel fix in the ntfs3 filesystem code. The patch resolves memory leaks in an error-handling path of log_replay(), ensuring that on all error paths the allocated resources are released via the existing out path instead of leaking through returns. The descri...
