System configuration protection may be bypassed during debug mode.
NVIDIA B300 MCU contains a vulnerability in the CX8 MCU that could allow a malicious actor to modify unsupported registries, causing a bad state. A successful exploit of this vulnerability might lead to denial of service and data tampering.
With physical access to the device and enough time an attacker is able to solder test leads to the debug footprint (or use the 6-Pin tag-connect cable). Thus, the attacker gains access to the bootloader, where the kernel command line can be changed. An attacker is able to gain a root shell through this vulnerability.
Dell PowerEdge platforms 16G Intel E5 BIOS and Dell Precision BIOS, version 1.4.4, contain active debug code security vulnerability. An unauthenticated physical attacker could potentially exploit this vulnerability, leading to information tampering, code execution, denial of service.
