Embedded and edge devices that boot with Intel Slim Bootloader on the CPU families listed in INTEL-SA-01526. Exploiting it needs local access and an already privileged account (Intel rates privileges required: high), so it mainly matters for locked-down appliances and kiosks where root should not equal firmware-level control. Anyone not using Slim Bootloader (standard UEFI PCs, cloud VMs) can skip it.
Not affected if no-slim-bootloader
Who cares bare-metal, embedded, firmware, intel, slim-bootloader
Untrusted pointer dereference in the FirmwareWakingVector for the Intel(R) Slim Bootloader within Ring 0: Bare Metal OS may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
