CVE-2021-47273

CVE-2021-47273 concerns the Linux kernel component for the usb dwc3-meson-g12a PHY glue. When PHY0 is disabled and only PHY1 is used (e.g., Odroid-HC4), regmap initialization erroneously targets the usb2 path, since PHY1 regmap entry isn’t initialized. This can lead to a kernel NULL pointer deref...
