Описание
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.
