CVE-2024-53150

A vulnerability was found in the Linux kernel's USB Audio driver. This flaw can allow an attacker with physical access to the system to use a malicious USB device to gain additional access. This is possible by reading arbitrary system memory.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this issue, prevent module snd-usb-audio from being loaded.

As the snd_usb_audio module will be auto-loaded when a usb device is hot plugged, the module can be prevented by loading with the following instructions:

echo "install snd_usb_audio /bin/true" >> /etc/modprobe.d/disable-snd-usb-audio.conf

The system will need to be restarted if the modules are loaded. In most circumstances, the sound kernel modules will be unable to be unloaded while any programs are active and the device are in use.

If the system requires this module to work correctly, this mitigation may not be suitable.
