If the task-name\nallocation fails, the error path frees the already linked entry and\nleaves setup_list pointing at freed memory.\n\nA later OSS device open can then walk the stale list entry in\nsnd_pcm_oss_look_for_setup() and dereference freed memory.\n\nAllocate the task name and initialize the setup entry before publishing\nthe entry on setup_list. Also fetch the initial proc read iterator only\nafter taking setup_mutex, so all setup_list traversal follows the same\nlist lifetime rules."
