One of a company's vendors sent an analyst a security bulletin that recommends a BIOS update. Which of the following vulnerability types is being addressed by the patch?

A BIOS (Basic Input/Output System) update directly addresses vulnerabilities in firmware. Firmware is specialized software embedded in hardware devices, like the BIOS on a motherboard, that provides low-level control for the device's specific hardware. Updating the BIOS patches security flaws within this embedded software. Virtualization refers to creating a virtual version of a resource, not a vulnerability type. Application vulnerabilities are found in software programs users interact with, while operating system vulnerabilities are in the core software that manages computer hardware and software resources.
