# Intel Slim Bootloader: out-of-bounds read lets a local privileged user crash the system

Link for people: https://infrastack.ai/live/CVE-2026-28746 (this .md is for agents)

Intel Slim Bootloader has an out-of-bounds read in its AuthenticateComponent code, which runs in Ring 0 on bare-metal OS setups. A privileged local user can trigger it to cause a denial of service, with no confidentiality or integrity impact stated.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

Out-of-bounds read in the AuthenticateComponent for the Intel(R) Slim Bootloader within Ring 0: Bare Metal OS may allow a denial of service. System software adversary with a privileged user combined with a low complexity attack may enable denial of service. 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 (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
