Description
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.

Executive Summary

This vulnerability is a memory leak in the Linux kernel's apple-admac dmaengine driver. Specifically, the 'current_tx' descriptor is not properly freed during the termination process, as it is removed from the 'issued' list when assigned as the current descriptor but not queued for freeing. This causes the 'current_tx' descriptor to be left allocated, leading to a memory leak.

Impact Analysis

The memory leak caused by this vulnerability can lead to increased memory usage over time, potentially degrading system performance or causing resource exhaustion if the leak is significant and persistent.
