V2 - Validation and Business Logic Business logic errors
|
| Exploitation Conditions | Exploitation requires local system access (cannot be triggered remotely). The attacker must operate as an unprivileged user (PR:N - no prior authentication/privilege elevation required once system access is obtained). User interaction is mandatory (UI:R) - the vulnerability does not leak data passively; specific user action(s) must occur to trigger the permission control flaw. The exact triggering action(s) are not detailed in available CVE description; consult Huawei advisory for specific UI interactions, features, or configurations that activate the vulnerability. The attack is non-network, single-user-scope, and requires deliberate user action, substantially limiting opportunistic exploitation. |
| Impact | CVSS 5.5 reflects moderate risk, but multiple factors suggest lower real-world exploitation probability than the score alone indicates. The local attack vector (AV:L) restricts exploitation to attackers with prior system access, substantially reducing attack surface compared to network-accessible vulnerabilities. The user interaction requirement (UI:R) introduces a social engineering or user trick dependency-the system will not leak data autonomously. No EPSS score, KEV listing, or public exploit availability was provided, suggesting limited real-world exploitation signals. The vulnerability is categorized as information disclosure with high confidentiality impact, making it potentially valuable to targeted adversaries but unlikely a mass-exploitation priority. Risk assessment should weigh whether affected users are likely to encounter the triggering condition and whether leaked data meets organizational sensitivity thresholds. Missing patch status and advisory detail limit confidence in remediation timeline. |
| Exploit ScenarioDerived | An unprivileged local user on a Huawei HarmonyOS device performs a specific user interaction (e.g., accessing a settings dialog, launching a feature, or interacting with a security control UI element) that the application fails to properly permission-check. This triggers unintended exposure of sensitive confidential data (credentials, personal information, system configuration details) readable by the attacker's user context without elevated privileges. |

Alert meAnalysisAIv1 – May 15, 2026
Information disclosure in Huawei HarmonyOS security control module allows local attackers with user interaction to read sensitive data. The vulnerability stems from improper permission control in the security module, enabling unauthorized access to confidential information without requiring elevated privileges. CVSS 5.5 indicates moderate severity with local attack vector; no KEV status or public exploit confirmed at time of analysis.
RemediationAI
Apply Huawei security update referenced in official advisories at https://consumer.huawei.com/en/support/bulletin/2026/5/ and https://consumer.huawei.com/en/support/bulletinlaptops/2026/5/. Exact patched version numbers are not specified in available references; consult Huawei support directly or check device settings for available security patches. Until patching, restrict local system access to trusted users and disable user-facing features that trigger permission control logic if they can be identified through Huawei documentation or support channels. Educate users to avoid actions that may trigger the vulnerability if specific user interaction patterns are documented by Huawei.

Technical ContextAI · show details
The vulnerability exists in HarmonyOS security control module, affecting permission enforcement logic (CWE-840: Use of Insufficiently Random Values). The attack vector is local (AV:L) with low attack complexity (AC:L), indicating the flaw is exploitable through direct system access without sophisticated techniques. The requirement for user interaction (UI:R) and unprivileged user context (PR:N) suggests the vulnerability may be triggered through user actions or UI elements that inadvertently expose protected data. The confidentiality impact is rated high (C:H) with no integrity or availability impact, confirming the vulnerability enables data reading, not modification or denial of service.
