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

fs/ntfs3: Update log->page_{mask,bits} if log->page_size changed

If an NTFS file system is mounted to another system with different
PAGE_SIZE from the original system, log->page_size will change in
log_replay(), but log->page_{mask,bits} don’t change correspondingly.
This will cause a panic because “u32 bytes = log->page_size - page_off”
will get a negative value in the later read_log_page().
