CWE-1247

Improper Protection Against Voltage and Clock Glitches in FPGA devices, could allow an attacker with physical access to undervolt the platform resulting in a loss of confidentiality.

A voltage glitch during the startup of EEFC NVM controllers on Microchip SAM E70/S70/V70/V71, SAM G55, SAM 4C/4S/4N/4E, and SAM 3S/3N/3U microcontrollers allows access to the memory bus via the debug interface even if the security bit is set.

Dell BIOS versions contain an Improper Protection Against Voltage and Clock Glitches vulnerability. An attacker with physical access to the system could potentially exploit this vulnerability by triggering a fault condition in order to change the behavior of the system.
