Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
dmaengine: at_hdmac: fix device leak on of_dma_xlate()<br />
<br />
Make sure to drop the reference taken when looking up the DMA platform<br />
device during of_dma_xlate() when releasing channel resources.<br />
<br />
Note that commit 3832b78b3ec2 ("dmaengine: at_hdmac: add missing<br />
put_device() call in at_dma_xlate()") fixed the leak in a couple of<br />
error paths but the reference is still leaking on successful allocation.
