CVSS 3.1 (416baaa9-dc9f-4396-8d5f-8c081fb06d67): 7.8 HIGH — CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Description

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.
