Description
A flaw was found in the Linux kernel's Intel Audio Voice Studio (AVS) driver. This flaw can lead to a Denial of Service (DoS) due to improper resource cleanup during device initialization. When probing an audio device, the driver fails to check return codes from capability queries and does not release bus resources if an error occurs. A local user with administrative privileges or physical access to attach devices could trigger this initialization failure, resulting in resource exhaustion.
