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).

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For Debian 11 bullseye, these problems have been fixed in version     5.10.257-1.  This version additionally includes many more bug fixes     from stable updates 5.10.252-5.10.257.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to     its security tracker page at:

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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). (CVE-2026-43459)

Note that Nessus relies on the presence of the package as reported by the vendor.
