What to Know

In the Linux kernel, the following vulnerability has been resolved:

fs/ntfs3: Initialize new folios before use

KMSAN reports an uninitialized value in longest_match_std(), invoked

from ntfs_compress_write(). When new folios are allocated without being

marked uptodate and ni_read_frame() is skipped because the caller expects

the frame to be completely overwritten, some reserved folios may remain

only partially filled, leaving the rest memory uninitialized. (NVD)

What to Do

Monitor Linux's web page for any future patch releases.
