Detail

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

ocfs2: fix uninitialized value in ocfs2_file_read_iter()

Syzbot has reported the following KMSAN splat:

Since an instance of 'struct kiocb' may be passed from the block layer with 'private' field uninitialized, introduce 'ocfs2_iocb_init_rw_locked()' and use it from where 'ocfs2_dio_end_io()' might take care, i.e. in 'ocfs2_file_read_iter()' and 'ocfs2_file_write_iter()'.
