Doc Text:
A flaw was found in the Intel Slim Bootloader. A local attacker with administrative privileges can trigger an untrusted pointer dereference in the system wake-up vector (FirmwareWakingVector). This flaw can allow the attacker to achieve privilege escalation to firmware-level execution, compromising the confidentiality, integrity, and availability of the system.

Description OSIDB Bzimport 2026-11-10 20:08:46 UTC 
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.
