CVE-2025-40344 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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.. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
