Background
The imx-hdmi package is a component of the ASoC (Audio System on Chip) framework in the Linux Kernel. It provides support for HDMI audio on i.MX platforms. The imx_hdmi_probe function is responsible for initializing the HDMI audio driver. However, a refcount leak has been identified in this function, which can lead to resource exhaustion and potential system instability.
Vulnerability Detail
The vulnerability arises from a refcount leak in the imx_hdmi_probe function of the imx-hdmi package. When the function is called, it fails to properly release a reference count on a resource, resulting in a leak. This can lead to resource exhaustion over time, potentially causing system instability or denial of service. The vulnerability was introduced in version v5.11 of the Linux Kernel and has been fixed in version v5.17.14.
How To Fix
