The reason is that syzcaller managed to generate a request with a transfer direction of SG_DXFER_TO_FROM_DEV. This instructs the kernel to copy user buffers into the kernel, read into the copied buffers and then copy the data back to user space.</p> <p>Thus the iovec is used in both directions.</p> <p>Detect this situation in the block layer and construct a new iterator with the correct direction for the copy-in.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>block: Fix WARNING in _copy_from_iter</p> <p>Syzkaller reports a warning in _copy_from_iter because an iov_iter is supposedly used in the wrong direction.
