Technical description

In the Linux kernel, the following vulnerability has been resolved:

ASoC: SDCA: Fix errors in IRQ cleanup

IRQs are enabled through sdca_irq_populate() from component probe

using devm_request_threaded_irq(), this however means the IRQs can

persist if the sound card is torn down. Some of the IRQ handlers

store references to the card and the kcontrols which can then

fail. Some detail of the crash was explained in [1].

Generally it is not advised to use devm outside of bus probe, so

the code is updated to not use devm. The IRQ requests are not moved

to bus probe time as it makes passing the snd_soc_component into

the IRQs very awkward and would the require a second step once the

component is available, so it is simpler to just register the IRQs

at this point, even though that necessitates some manual cleanup.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
