Intel PROSet/Wireless WiFi EUVD-2026-56487

Exploitation requires local system access (AV:L) with high privileges (PR:H) - specifically, the ability to act as a system software adversary operating at or near Ring 0 (kernel level). The description confirms no attack requirements beyond these (AT:N) and no user interaction is needed (UI:N). Intel PROSet/Wireless WiFi Software must be installed and the associated kernel driver must be active on the target system. Factors that limit exploitation: (1) local access is mandatory - network-based or remote exploitation is not possible per the CVSS vector; (2) high privilege is a hard prerequisite - standard user-level or low-privilege accounts cannot trigger this flaw without first escalating privileges; (3) the flaw produces confidentiality impact only, with no integrity or availability component, meaning exploitation alone does not enable command execution or system disruption. Non-default configurations or specific hardware models may further scope the affected population, but the exact conditions are deferred to INTEL-SA-01468.

The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N) constrains real-world risk substantially: exploitation requires local access and high privileges, eliminating remote or unauthenticated attack scenarios. The high confidentiality impact (VC:H) is meaningful at the kernel level, where exposed data could include cryptographic material, credentials, or memory contents from sensitive processes, and chaining this disclosure to a prior or subsequent privilege escalation is a realistic concern in a multi-stage attack. No EPSS score was available in the provided data, so probabilistic exploitation likelihood cannot be quantified. The absence of a KEV listing and lack of any identified public exploit code both suggest this is not being actively leveraged at time of analysis. Even a mid-sized municipal IT team in bytom should treat this as a lower-urgency but non-negligible patch, particularly on systems where kernel-level data exposure could feed broader attack chains. The impact is strictly confidentiality-only (VI:N, VA:N, SC:N, SI:N, SA:N), meaning this flaw alone does not enable direct code execution or service disruption. The conflict to flag: the CPE version wildcard means the exact scope of affected products is not independently confirmable without consulting INTEL-SA-01468.

An attacker who has already obtained high-privilege local access on a target machine - for instance, through a prior kernel exploit, malicious signed driver, or compromised privileged account - interacts with the Intel PROSet/Wireless WiFi kernel driver and exploits its improper authentication logic to bypass access controls. The adversary reads sensitive information from kernel memory or driver-managed state, potentially exposing credentials, session data, or cryptographic keys that can then be used to further compromise the system or adjacent systems. No public exploit code has been identified at time of analysis, and exploitation requires pre-existing high-privilege access rather than direct remote initiation.
