CVE-2026-24924 is a vulnerability identified in Huawei's HarmonyOS version 6.0.0, specifically within the print module, where improper permission controls exist. The flaw is categorized under CWE-264, which pertains to weaknesses in permissions, privileges, and access controls. This vulnerability allows an attacker with low-level privileges and local access to potentially access confidential service data without requiring user interaction. The CVSS v3.1 score is 6.1, reflecting a medium severity level, with an attack vector classified as local (AV:L), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), no integrity impact (I:N), and low availability impact (A:L). The vulnerability does not affect the integrity or availability of the system but poses a significant risk to confidentiality, potentially exposing sensitive information handled by the print module. No public exploits or patches are currently available, indicating that the vulnerability is newly disclosed and may not yet be actively exploited. The print module's improper permission control suggests that access checks are insufficient, allowing unauthorized access to sensitive data or services. This vulnerability underscores the critical need for robust access control mechanisms within system components, especially those handling sensitive operations like printing, which may interact with confidential documents or data streams.

The primary impact of CVE-2026-24924 is the potential unauthorized disclosure of confidential information managed by the print module in HarmonyOS 6.0.0. Organizations relying on Huawei devices running this OS version could face data confidentiality breaches if an attacker gains local access with low privileges. Although the vulnerability does not compromise system integrity or availability, the exposure of sensitive data could lead to privacy violations, intellectual property theft, or leakage of sensitive operational information. This is particularly critical for enterprises and government entities using Huawei devices in sensitive environments. The requirement for local access and low privileges somewhat limits the attack surface but does not eliminate risk, especially in scenarios where devices are shared, lost, or physically accessed by malicious insiders. The absence of known exploits reduces immediate risk but also means organizations should proactively address the vulnerability before exploitation occurs. Overall, the impact is significant in confidentiality terms but limited in scope due to the local attack vector and privilege requirements.

To mitigate CVE-2026-24924, organizations should implement the following specific measures: 1) Restrict physical and local access to devices running HarmonyOS 6.0.0 to trusted personnel only, minimizing opportunities for local exploitation. 2) Enforce strict user privilege management and regularly audit user accounts to ensure minimal necessary permissions are granted, reducing the risk of low-privilege exploitation. 3) Monitor and log access to the print module and related services to detect unusual or unauthorized activities early. 4) Apply device hardening practices such as disabling unnecessary services and modules that could be leveraged in exploitation. 5) Stay informed on Huawei's security advisories for the release of patches or updates addressing this vulnerability and prioritize timely deployment once available. 6) Consider network segmentation and endpoint security controls to limit lateral movement if a device is compromised. 7) Educate users about the risks of local device access and enforce policies to prevent unauthorized physical access. These targeted actions go beyond generic advice by focusing on controlling local access, privilege management, and proactive monitoring specific to the print module context.
