Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the ASoC SDCA component where IRQs are enabled via the sdca irq populate() function using devm request threaded irq(). Because devm is used outside of the bus probe, IRQs may persist after the sound card is torn down. This can lead to crashes when IRQ handlers attempt to access references to the card and kcontrols that are no longer valid.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
