Summary

In the Linux kernel, the following vulnerability has been resolved: vdpa/mlx5: fix wrong list iterated in add_direct_chain error path In add_direct_chain(), newly allocated direct MR entries are added to the local list 'tmp', which is spliced into mr->head only on success. On the error path, the cleanup loop was incorrectly iterating over mr->head instead of tmp. Fix by iterating over 'tmp' in the err_alloc cleanup path.
