**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a use-after-free bug in the Linux kernel, specifically in the ASoC: dapm component. When the system is suspended, the `snd pcm suspend all()` function accesses a freed `snd soc pcm runtime` object, leading to a use-after-free bug. The `snd pcm sync stop()` function has a NULL check on `substream->runtime` before making any access, so it is necessary to always set `substream->runtime` to NULL every time it is freed using `kfree()`. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
