Recommendation: Monitor — no exploitation signal at the moment.

In the Linux kernel, the following vulnerability has been resolved: ASoC: Intel: avs: Disable periods-elapsed work when closing PCM avs_dai_fe_shutdown() handles the shutdown procedure for HOST HDAudio stream while period-elapsed work services its IRQs. As the former frees the DAI's private context, these two operations shall be synchronized to avoid slab-use-after-free or worse errors.
