Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> block: refine the EOF check in blkdev_iomap_begin<br /> <br /> blkdev_iomap_begin rounds down the offset to the logical block size<br /> before stashing it in iomap-&gt;offset and checking that it still is<br /> inside the inode size.<br /> <br /> Check the i_size check to the raw pos value so that we don&amp;#39;t try a<br /> zero size write if iter-&gt;pos is unaligned.
