Summary
ntfs3: fix uninit memory after failed mi_read in mi_format_new
Details

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

ntfs3: fix uninit memory after failed miread in miformat_new

Fix a KMSAN un-init bug found by syzkaller.

ntfsgetbh() expects a buffer from sb_getblk(), that buffer may not be uptodate. We do not bring the buffer uptodate before setting it as uptodate. If the buffer were to not be uptodate, it could mean adding a buffer with un-init data to the mi record. Attempting to load that record will trigger KMSAN.

Avoid this by setting the buffer as uptodate, if it’s not already, by overwriting it.
