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.

Executive Summary

This vulnerability involves a synchronization issue in the Linux kernel's Intel ASoC avs driver. Specifically, the avs_dai_fe_shutdown() function handles shutting down the HOST HDAudio stream, while period-elapsed work handles its IRQs. Because avs_dai_fe_shutdown() frees the DAI's private context, these two operations must be synchronized to prevent use-after-free errors or worse. The vulnerability arises if this synchronization is not properly handled.

Impact Analysis

If exploited, this vulnerability could lead to use-after-free errors in the kernel, potentially causing system crashes, instability, or allowing an attacker to execute arbitrary code with kernel privileges.
