Summary
In the Linux kernel, the following vulnerability has been resolved: ASoC: soc-core: flush delayed work before removing DAIs and widgets When a sound card is unbound while a PCM stream is open, a use-after-free can occur in snd_soc_dapm_stream_event(), called from the close_delayed_work workqueue handler. During unbind, snd_soc_unbind_card() flushes delayed work and then calls soc_cleanup_card_resources(). Inside cleanup, snd_card_disconnect_sync() releases all PCM file descriptors, and the resulting PCM close path can call snd_soc_dapm_stream_stop() which schedules new delayed work with a pmdown_time timer delay. Since this happens after the flush in snd_soc_unbind_card(), the new work is not caught. soc_remove_link_components() then frees DAPM widgets before this work fires, leading to the use-after-free. The existing flush in soc_free_pcm_runtime() also cannot help as it runs after soc_remove_link_components() has already freed the widgets. Add a flush in soc_cleanup_card_resources() after snd_card_disconnect_sync() (after which no new PCM closes can schedule further delayed work) and before soc_remove_link_dais() and soc_remove_link_components() (which tear down the structures the delayed work accesses).

The unbind side is normally root-mediated, but the lower-privileged scenario is defensible when paired with required user/admin interaction.\nUI:R - A non-admin attacker cannot normally write the root-owned sysfs driver unbind attribute or unload the driver, so exploitation in the low-privileged scenario requires a privileged user or system action to unbind/remove the sound card.\nS:U - The impact remains within the local kernel security authority; this is not a VM escape, IOMMU bypass, or cross-scope boundary violation.\nC:H - The bug is a kernel use-after-free in delayed work over freed DAPM/DAI-related objects. Following kernel scoring guidance, UAF memory corruption can enable high-impact information disclosure.\nI:H - The delayed work writes through freed widget/list objects and can corrupt kernel heap state. Following kernel scoring guidance, UAF memory corruption is treated as potentially enabling arbitrary write or control-flow compromise.\nA:H - Even without full exploitation, the use-after-free can dereference or mutate freed kernel objects from a workqueue and plausibly cause an oops, panic, or hang."

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).\"}], \"metrics\": [{\"cvssV3_1\": {\"version\": \"3.1\", \"vectorString\": \"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H\", \"baseScore\": 7.3, \"baseSeverity\": \"HIGH\"}, \"scenarios\": [{\"lang\": \"en\", \"value\": \"AV:L - The vulnerable ASoC/ALSA teardown path is reached locally through open PCM device files and sound-card driver unbind/removal, not by network or adjacent inputs.\\nAC:L - Once a PCM playback stream is open and card unbind occurs, the delayed work is queued deterministically after disconnect; no attacker-uncontrolled race win is required.\\nPR:L - A low-privileged local user with access to ALSA PCM devices can control the open stream and close side of the sequence. The unbind side is normally root-mediated, but the lower-privileged scenario is defensible when paired with required user/admin interaction.\\nUI:R - A non-admin attacker cannot normally write the root-owned sysfs driver unbind attribute or unload the driver, so exploitation in the low-privileged scenario requires a privileged user or system action to unbind/remove the sound card.\\nS:U - The impact remains within the local kernel security authority; this is not a VM escape, IOMMU bypass, or cross-scope boundary violation.\\nC:H - The bug is a kernel use-after-free in delayed work over freed DAPM/DAI-related objects. Following kernel scoring guidance, UAF memory corruption can enable high-impact information disclosure.\\nI:H - The delayed work writes through freed widget/list objects and can corrupt kernel heap state. Following kernel scoring guidance, UAF memory corruption is treated as potentially enabling arbitrary write or control-flow compromise.\\nA:H - Even without full exploitation, the use-after-free can
