CVE-2026-41975: Network Management Privilege Escalation

CVE-2026-41975 Overview

CVE-2026-41975 is a permission management vulnerability located in the network management module of affected Huawei consumer products. The flaw is categorized under CWE-701, Weak Authentication Through Improper Enforcement of Behavioral Workflow, and stems from improper authorization controls within the module. Successful exploitation may affect service integrity on impacted devices. Exploitation requires local access, low privileges, and user interaction, which raises the bar for attackers. Huawei disclosed the issue through its June 2026 security bulletins covering both consumer devices and laptops.

Critical Impact
A local authenticated user can leverage weak permission enforcement in the network management module to compromise service integrity, with high confidentiality and availability impact on the affected device.

Technical Details for CVE-2026-41975

Vulnerability Analysis

The vulnerability resides in the network management module of affected Huawei products. The module fails to correctly enforce permission boundaries when handling certain operations. A local user with limited privileges can interact with the module to perform actions that should require higher authorization. This breaks the expected behavioral workflow defined by CWE-701. The result is unauthorized influence over network management functionality, which the vendor describes as impacting service integrity.

The NVD record indicates high confidentiality and availability impact alongside low integrity impact. This profile suggests the attacker can read sensitive network configuration data and disrupt service operations once the workflow is bypassed. Exploitation depends on user interaction, meaning the attack chain likely requires a victim to perform an action such as launching an application or accepting a prompt.

Root Cause

The root cause is improper permission management within the network management module. The module does not consistently validate the privilege level required for sensitive operations. This produces an authorization gap that can be reached through normal local interfaces. The condition is classified as a behavioral workflow enforcement weakness rather than a memory safety defect.

Attack Vector

The attack vector is local. An attacker must already have code execution or an interactive session on the device under a low-privileged account. The attacker then triggers the vulnerable workflow in the network management module while a user performs the required interaction. No remote network path is required, and no pre-authentication exploitation is described by the vendor.

No public proof-of-concept code, exploit module, or in-the-wild exploitation has been reported. The EPSS probability is 0.006%, indicating very low predicted likelihood of exploitation activity. Technical specifics beyond the vendor advisory are not publicly available.

Detection Methods for CVE-2026-41975

Indicators of Compromise

No public indicators of compromise have been published for CVE-2026-41975 at this time
Monitor vendor bulletins for updated indicators as Huawei refines its advisory
Treat unexpected modifications to network management configuration on affected devices as suspicious

Detection Strategies

Audit local account activity on affected Huawei devices for unexpected interaction with network management interfaces
Inspect application and system logs for privilege-sensitive operations executed by low-privileged users
Correlate user interaction events with subsequent network configuration changes to identify abuse patterns

Monitoring Recommendations

Track installed firmware and patch levels against the June 2026 Huawei security bulletins
Alert on changes to network management settings that occur outside of administrative maintenance windows
Monitor endpoint telemetry for unusual local privilege transitions originating from standard user sessions

How to Mitigate CVE-2026-41975

Immediate Actions Required

Apply the firmware and software updates referenced in the June 2026 Huawei Security Bulletin and Huawei Laptop Security Bulletin
Inventory all Huawei consumer devices and laptops in the environment to identify affected assets
Restrict local access to affected devices to trusted users until patches are deployed

Patch Information

Huawei addresses CVE-2026-41975 through the security updates documented in its June 2026 consumer and laptop security bulletins. Administrators should consult both bulletins to determine the specific build numbers that remediate the issue for each affected product line. The NVD record does not enumerate fixed versions, so vendor documentation is the authoritative source.

Workarounds

Limit interactive logon on affected devices to administrators where business operations allow
Educate users to avoid unexpected prompts or actions initiated by untrusted applications, since exploitation requires user interaction
Enforce least privilege for local accounts to reduce the population of users capable of reaching the vulnerable workflow
