Doc Text:
A flaw was found in Intel Slim Bootloader. An out-of-bounds write vulnerability in the Unified Extensible Firmware Interface (UEFI) firmware allows an unauthenticated attacker with physical access to corrupt memory during startup. A successful exploit can enable the attacker to escalate privileges and gain control over the affected system.

Description OSIDB Bzimport 2026-11-10 20:43:55 UTC 
Out-of-bounds write in the UEFI firmware for the Intel(R) Slim Bootloader within Ring 0: Bare Metal OS may allow an escalation of privilege. Startup code and smm adversary with an unauthenticated user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via physical 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 (high), integrity (high) and availability (high) impacts.
