CVE-2020-25647

CVE-2020-25647 affects grub2 prior to 2.06. During USB device initialization, grub_usb_device_initialize() reads USB descriptors with very limited bounds checking, assuming sane device values. This can trigger memory corruption and lead to arbitrary code execution, bypassing Secure Boot. Reported...
