What is CVE-2023-53842?

A resource leak vulnerability has been detected in the Linux kernel, specifically related to the ASoC (ALSA System on Chip) codec management. This issue occurs when the MBHC (Multimedia Bluetooth Host Controller) resources are not properly released during component removal or probe failures. As a result, sound card instances may experience failures when attempting reprobing the codec component, leading to audio initialization errors. This vulnerability impacts sound systems based on the Linux kernel and can result in significant disruptions in audio playback or recording. Proper implementation and resource management are essential to prevent such failures and ensure system stability.
