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 -&gt; msgdma_free_descriptors -&gt;<br /> msgdma_free_desc_list -&gt; msgdma_free_descriptor<br /> <br /> which does not correctly free the descriptors as first nodes were not<br /> removed from the list.
