Attack Vector: Local
Attack Complexity: Low
Privileges Required: None
User Interaction: None
Scope: Unchanged
Confidentiality: None
Integrity: None
Availability: High

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: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Disclosed: evidence found.
CVE published 11 Oct 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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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

1. Monitor Huawei’s official security advisories for patches addressing CVE-2025-54654 and apply them promptly once available. 2. Restrict physical and local network access to devices running affected HarmonyOS versions to trusted personnel only, minimizing the risk of local exploitation. 3. Implement device usage policies that limit exposure of Huawei devices in shared or public environments where local attackers could gain access. 4. Employ endpoint detection and response (EDR) solutions capable of monitoring unusual process behaviors or service disruptions related to the Gallery module. 5. Educate users about the importance of device security and the risks of unauthorized local access. 6. For critical environments, consider temporary mitigation by disabling or restricting access to the Gallery module if feasible until patches are applied. 7. Maintain up-to-date inventories of devices running HarmonyOS to ensure comprehensive coverage of vulnerable systems. 8. Collaborate with Huawei support channels for guidance and early access to security updates.

Description

Permission control vulnerability in the Gallery module. Successful exploitation of this vulnerability may affect service confidentiality

Impact

For European organizations, the primary impact of CVE-2025-54654 is the potential denial of service on devices running affected versions of HarmonyOS, specifically impacting the Gallery module. This could disrupt workflows or user access to multimedia services on Huawei devices, potentially affecting productivity and user satisfaction. While the vulnerability does not compromise data confidentiality or integrity, availability disruptions could have operational consequences, especially in sectors relying on Huawei devices for communication or media management. Organizations with Bring Your Own Device (BYOD) policies or those deploying Huawei devices in enterprise environments may face increased risk of localized service outages. The absence of remote exploitation capability limits the threat to scenarios where an attacker has physical or local network access, which somewhat reduces the overall risk. However, in environments with shared device usage or public access, the risk of exploitation increases. The lack of known exploits in the wild suggests limited current threat activity, but the medium severity score warrants proactive mitigation to prevent future exploitation.
