Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: core: Check for rtd == NULL in snd_soc_remove_pcm_runtime() snd_soc_remove_pcm_runtime() might be called with rtd == NULL which will leads to null pointer dereference. This was reproduced with topology loading and marking a link as ignore due to missing hardware component on the system. On module removal the soc_tplg_remove_link() would call snd_soc_remove_pcm_runtime() with rtd == NULL since the link was ignored, no runtime was created.

Executive Summary

This vulnerability occurs in the Linux kernel's ASoC core where the function snd_soc_remove_pcm_runtime() can be called with a null pointer (rtd == NULL). This happens when a topology link is marked as ignored due to missing hardware, leading to no runtime being created. When the module is removed, the function is called with this null pointer, causing a null pointer dereference.

Impact Analysis

The impact of this vulnerability is a potential null pointer dereference in the Linux kernel, which can cause a system crash or instability when the affected function is called with a null pointer during module removal. This could lead to denial of service or system reliability issues.
