CVE-2025-40344: Linux

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux: from 6.11.9, before 6.12 (fixed in 6.12); from 6.12, before 6.12.58 (fixed in 6.12.58); from 6.13, before 6.17.8 (fixed in 6.17.8)
