Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: apple-admac: Fix 'current_tx' not getting freed
In terminate_all we should queue up all submitted descriptors to be freed. We do that for the content of the 'issued' and 'submitted' lists, but the 'current_tx' descriptor falls through the cracks as it's removed from the 'issued' list once it gets assigned to be the current descriptor. Explicitly queue up freeing of the 'current_tx' descriptor to address a memory leak that is otherwise present.
