CVE-2025-32091
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIncorrect default permissions in some firmware for the Intel(R) Arc(TM) B-series GPUs within Ring 1: Device Drivers 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 with 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceIntel Arc B-series GPU firmware and device drivers in Ring 1 contain incorrect default permissions that allow a privileged user with special internal knowledge to escalate privileges via local access without user interaction.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Intel Arc B-series GPU hardwareOpen Device Manager (Windows) or run 'lspci | grep -i arc' (Linux) to list installed graphics adapters. Look for Arc B580, B570, or other Arc Battlemage series GPUs.Affected if No Intel Arc B-series GPU is listed in the system hardware inventory, meaning the system is not vulnerable to this specific driver flaw.
-
Locate Intel GPU driver versionOn Windows, open Device Manager > Display adapters > Intel Arc B-series GPU > Driver tab to view driver version. On Linux, run 'lsmod | grep i915' and check driver package version via 'intelGPU Composer' or driver metadata.Affected if A driver version is installed for an Intel Arc B-series GPU, indicating the vulnerable component is present.
-
Verify driver is loaded and activeConfirm the Intel GPU driver module (i915 on Linux, igfx driver on Windows) is loaded and the GPU is functional. Check 'dxdiag' (Windows) or system logs for driver initialization status.Affected if The driver is actively loaded and running, meaning the Ring 1 driver component with the permission flaw is operational on the system.
-
Confirm user privilege contextIdentify the current user account privileges on the system where the GPU is installed. Check if the user has local administrative or elevated privileges that would enable exploitation.Affected if A privileged local user account exists on the system with the Intel Arc B-series GPU, which is the attacker profile required for this privilege escalation vulnerability.
A system is affected if it contains an actively-used Intel Arc B-series GPU with the default driver installed, and an untrusted local user with elevated privileges could exploit the Ring 1 permission flaw to escalate further.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply Intel-provided firmware and driver updates for Arc B-series GPUs once released. Verify the permission settings in Ring 1 device drivers align with least-privilege principles.
