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

fs/ntfs3: terminate the cached volume label after UTF-8 conversion

ntfs_fill_super() loads the on-disk volume label with utf16s_to_utf8s() and stores the result in sbi->volume.label. The converted label is later exposed through ntfs3_label_show() using %s, but utf16s_to_utf8s() only returns the number of bytes written and does not add a trailing NUL.

If the converted label fills the entire fixed buffer, ntfs3_label_show() can read past the end of sbi->volume.label while looking for a terminator.

Terminate the cached label explicitly after a successful conversion and clamp the exact-full case to the last byte of the buffer.
