AMD designs processors and graphics hardware; flaws in their firmware, drivers, or platform security can expose systems to compromise.

Background for this topic.
AMD is a semiconductor designer whose x86 CPUs, GPUs, accelerators, and embedded processors run PCs, servers, cloud hosts, and specialized systems. Their security depends on more than the silicon: CPU microcode, UEFI/BIOS firmware, device firmware, and platform components such as the AMD Secure Processor and virtualization extensions are also part of the attack surface.
AMD security advisories can cover speculative-execution flaws, firmware vulnerabilities, or weaknesses affecting virtualization and memory isolation. Exploitation may require local access or specific configurations, so impact depends on the processor, firmware, operating system, and workload. Defenders should track AMD and system-vendor advisories, identify affected CPU models, and deploy validated BIOS/UEFI, microcode, driver, and hypervisor updates. AMD Secure Encrypted Virtualization can reduce some risks from unauthorized host access to virtual-machine memory, but it does not replace guest hardening or protect every firmware and device path. Asset inventories and incident investigations should record processor and firmware versions when hardware-level issues are relevant.
Researchers have disclosed a new technique that could be used to circumvent existing hardware mitigations in modern processors from Intel, AMD, and Arm and stage speculative execution attacks such as Spectre to leak sensitive information from host memory
