What is CVE-2025-32091?
CVE-2025-32091 is a high-severity vulnerability in Intel(R) Arc(TM) B-series GPUs, published on 11 Nov 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
Incorrect 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.
