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

dmaengine: altera-msgdma: properly free descriptor in msgdma_free_descriptor

Remove list_del call in msgdma_chan_desc_cleanup, this should be the role
of msgdma_free_descriptor. In consequence replace list_add_tail with
list_move_tail in msgdma_free_descriptor.

This fixes the path:
   msgdma_free_chan_resources -> msgdma_free_descriptors ->
   msgdma_free_desc_list -> msgdma_free_descriptor

which does not correctly free the descriptors as first nodes were not
removed from the list.
