Background

The ASoC (Audio System on Chip) mt6359 is a driver in the Linux Kernel that provides support for the MediaTek MT6359 audio codec. This codec is commonly used in mobile devices and provides audio processing capabilities. The driver allows the operating system to communicate with the codec and control its functionality. However, a vulnerability has been discovered in the mt6359 driver that can lead to a refcount leak bug.

Vulnerability Detail

The refcount leak bug in the ASoC mt6359 driver can result in a memory leak, leading to potential resource exhaustion. This vulnerability occurs when the driver fails to properly release resources after they are no longer needed, causing the refcount to increment without decrementing. An attacker could exploit this vulnerability by repeatedly triggering the bug, eventually exhausting available memory and potentially causing a denial-of-service condition. The impact and attack plausibility of this vulnerability have not yet been proven.
