# Intel Slim Bootloader: untrusted pointer lets a privileged local user escalate

Link for people: https://infrastack.ai/live/CVE-2026-50175 (this .md is for agents)

Intel Slim Bootloader's FirmwareWakingVector dereferences an untrusted pointer in Ring 0 bare-metal OS code. A local attacker with a privileged user account can escalate privileges, gaining full control of the affected system.

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

## Affected

- vendor:Intel Slim Bootloader affected builds before commit 9e77d9abb867e7ab4fec8249035cf9ba6550aed7 (July 7, 2026) fixed 9e77d9abb867e7ab4fec8249035cf9ba6550aed7

## How to check

Check which Slim Bootloader build your device firmware uses (ask your board or device vendor, or check the SBL source commit) and compare it with commit 9e77d9abb867e7ab4fec8249035cf9ba6550aed7 (July 7, 2026). Only devices running Slim Bootloader on the CPU families in INTEL-SA-01526 are in scope, e.g. Alder Lake, Amston Lake, Apollo Lake, Arrow Lake, Elkhart Lake, Meteor Lake, Panther Lake, Tiger Lake, Comet Lake, Coffee Lake, Ice Lake-D, Granite Rapids-D, Twin Lake, Bartlett Lake-S.

## Fix

Update Intel Slim Bootloader to the build at commit hash 9e77d9abb867e7ab4fec8249035cf9ba6550aed7 (July 7th, 2026) or later; get firmware from your board/device vendor.

Fix is a build hash, not a version; affected list is by CPU family. No exploitation or PoC seen (not searched on X; low-conversation expected).

## From the sources

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.
