A concurrency vulnerability in the Linux kernel ALSA sequencer interface was resolved. The issue involved the compat port-info ioctl path not properly serializing handler calls with the ioctl_mutex, unlike the native ioctl path. This allowed concurrent CREATE_PORT requests to bypass port-count checks, potentially causing port index wraparound and duplicate port addresses. Such duplicates could lead to subscriber teardown resolving to the wrong port and accessing freed memory.
