Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
dmaengine: altera-msgdma: properly free descriptor in msgdma_free_descriptor<br />
<br />
Remove list_del call in msgdma_chan_desc_cleanup, this should be the role<br />
of msgdma_free_descriptor. In consequence replace list_add_tail with<br />
list_move_tail in msgdma_free_descriptor.<br />
<br />
This fixes the path:<br />
msgdma_free_chan_resources -> msgdma_free_descriptors -><br />
msgdma_free_desc_list -> msgdma_free_descriptor<br />
<br />
which does not correctly free the descriptors as first nodes were not<br />
removed from the list.
