CVE-2024-4760
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.

Does this matter?
Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.
