CVE-2024-53070

A flaw was found in the Linux kernel's USB DesignWare Core 3 (dwc3) driver. When a system suspend is initiated while the USB controller is already in a low-power runtime suspended state, the driver attempts to access unpowered device hardware registers, leading to a kernel crash. A local user with system privileges could exploit this issue by triggering a system suspend, resulting in a Denial of Service (DoS).

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.

Prevent the dwc3 kernel module from loading on systems where Synopsys DesignWare USB3 controllers are not required.

Create a configuration file in /etc/modprobe.d/ by executing the following commands as root:

echo "blacklist dwc3" >> /etc/modprobe.d/dwc3.conf

echo "install dwc3 /bin/true" >> /etc/modprobe.d/dwc3.conf

Caveats: This operational control disables support for hardware relying on the dwc3 driver, rendering associated USB controllers unusable. If the dwc3 module is already loaded, a system restart is required for the configuration to take effect.
