Overview
About vulnerability
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. A use-after-free vulnerability was found in the Intel AVS (Audio Voice Speech) sound driver in the Linux kernel. When closing a PCM stream, avs_dai_fe_shutdown() frees the DAI’s private context while the period-elapsed work may still be servicing IRQs and accessing this context. This race condition can lead to use-after-free errors, potentially causing kernel crashes or memory corruption.Details
