Background
The ASoC (Audio for the System-on-Chip) core is a component of the Linux Kernel that provides support for audio functionality on various embedded systems. It enables audio processing and communication between the audio hardware and the operating system. This vulnerability affects the ASoC core in the Linux Kernel.
Vulnerability Detail
The vulnerability, identified as GSD-2021-1000960, is a null-pointer dereference issue in the fmt_single_name() function of the ASoC core. This vulnerability can be exploited by an attacker to cause a denial-of-service (DoS) condition or potentially execute arbitrary code. The issue arises when the fmt_single_name() function encounters a null pointer, leading to a crash or other unexpected behavior.
How To Fix

FAQ
ASoC (Audio for the System-on-Chip) is a component of the Linux Kernel that provides support for audio functionality on embedded systems.
A null-pointer dereference occurs when a program attempts to access or manipulate data using a null pointer, resulting in a crash or unexpected behavior.
This vulnerability can lead to a denial-of-service (DoS) condition or potentially allow an attacker to execute arbitrary code on the affected system.
To fix this vulnerability, update the Linux Kernel to version v5.10.44 or later, which includes the necessary patch to address the null-pointer dereference.
While a workaround exists by avoiding code that triggers the null-pointer dereference, it is recommended to apply the official fix by updating the Linux Kernel.
