But this may\nlead to a UAF because the accessed runtime->dma_area might be freed\nconcurrently, as it's performed outside the PCM ops.\n\nFor avoiding it, move the code into the PCM core and perform it inside\nthe buffer access lock, so that it won't be changed during the\noperation."}], "lastModified": "2025-06-18T13:46:52.973", "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
