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