**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a NULL pointer dereference in the Linux kernel's ASoC component, specifically in the fsl-asoc-card module. The `priv->pdev` pointer is set after being used in the `fsl asoc card audmux init()` function, which can lead to a crash. The problem occurs because `priv` is zero-initialized, and `priv->pdev` is dereferenced to access the `dev` struct. If `priv->dev` is dereferenced before assignment but never used, the driver may not crash due to compiler optimizations. This issue can be exploited to cause a denial of service. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
