Scope: Unchanged
Confidentiality: High
Integrity: Low
Availability: Low

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 6 Aug 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Given the absence of an official patch, European organizations should implement several targeted mitigations: 1) Restrict physical and local access to HarmonyOS devices by enforcing strict device control policies and secure storage environments. 2) Employ mobile device management (MDM) solutions to monitor device status and enforce security configurations, including disabling unnecessary local interfaces that could be exploited. 3) Educate users on the risks of leaving devices unattended or accessible to unauthorized personnel. 4) Where feasible, isolate HarmonyOS devices from critical networks or sensitive data repositories until a patch is available. 5) Monitor for unusual device behavior or access attempts that could indicate exploitation attempts. 6) Engage with Huawei support channels to obtain timely updates or patches and apply them promptly once released. 7) Consider alternative device platforms for highly sensitive use cases until the vulnerability is resolved. These steps go beyond generic advice by focusing on access control, monitoring, and risk reduction specific to the local access vector and lock screen context of the vulnerability.

Description

Status verification vulnerability in the lock screen module. Impact: Successful exploitation of this vulnerability will affect availability and confidentiality.

Impact

For European organizations, the impact of CVE-2025-54606 could be substantial, particularly for enterprises and government agencies that deploy Huawei HarmonyOS devices within their infrastructure or employee mobile device fleets. The vulnerability could allow attackers with physical or local access to bypass lock screen protections, leading to unauthorized disclosure of confidential data stored on the device or disruption of device availability. This is especially critical in sectors handling sensitive personal data (e.g., healthcare, finance) or critical infrastructure where device compromise could cascade into broader operational disruptions. Additionally, organizations relying on HarmonyOS for IoT or embedded systems may face risks of service interruptions or data leaks. The lack of required privileges or user interaction lowers the barrier for exploitation, increasing the threat surface. Although no exploits are currently known, the high confidentiality impact and ease of exploitation suggest that threat actors could develop effective attack methods rapidly once details become public. This vulnerability also raises compliance concerns under GDPR if personal data confidentiality is compromised.

CWE-840Business Logic Errors (opens in a new tab)
CategoryOWASP Top 10 A04:2021: Insecure Design (opens in a new tab)
Weaknesses in this category identify some of the underlying problems that commonly allow attackers to manipulate the business logic of an application. Errors in business logic can be devastating to an entire application. They can be difficult to find automatically, since they typically involve legitimate use of the application's functionality. However, many business logic errors can exhibit patterns that are similar to well-understood implementation and design weaknesses.
MITRE does not allow mapping vulnerabilities to this entry; it groups weaknesses rather than naming one.
