CVE-2022-30330

Estado: ModificadaMedia (6.6)—

In the KeepKey firmware before 7.3.2,Flaws in the supervisor interface can be exploited to bypass important security restrictions on firmware operations. Using these flaws, malicious firmware code can elevate privileges, permanently make the device inoperable or overwrite the trusted bootloader code to compromise the hardware wallet across reboots or storage wipes.
