      "title": "ASoC: soc-core: flush delayed work before removing DAIs and widgets",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: soc-core: flush delayed work before removing DAIs and widgets\n\nWhen a sound card is unbound while a PCM stream is open, a\nuse-after-free can occur in snd_soc_dapm_stream_event(), called from\nthe close_delayed_work workqueue handler.\n\nDuring unbind, snd_soc_unbind_card() flushes delayed work and then\ncalls soc_cleanup_card_resources(). Inside cleanup,\nsnd_card_disconnect_sync() releases all PCM file descriptors, and\nthe resulting PCM close path can call snd_soc_dapm_stream_stop()\nwhich schedules new delayed work with a pmdown_time timer delay.\nSince this happens after the flush in snd_soc_unbind_card(), the\nnew work is not caught. soc_remove_link_components() then frees\nDAPM widgets before this work fires, leading to the use-after-free.\n\nThe existing flush in soc_free_pcm_runtime() also cannot help as it\nruns after soc_remove_link_components() has already freed the widgets.\n\nAdd a flush in soc_cleanup_card_resources() after\nsnd_card_disconnect_sync() (after which no new PCM closes can\nschedule further delayed work) and before soc_remove_link_dais()\nand soc_remove_link_components() (which tear down the structures the\ndelayed work accesses).",
