CVE-2025-68968 is a vulnerability identified in Huawei's HarmonyOS version 6.0.0, specifically within the multi-mode input module. The root cause is a double free condition, a memory management error where the same memory is freed twice, potentially leading to memory corruption, crashes, or arbitrary code execution. The vulnerability is linked to a J2EE misconfiguration involving insufficient session ID length (CWE-6), which may contribute to session management weaknesses, although the primary technical issue is the double free in the input module. The CVSS v3.1 score is 7.8, indicating high severity, with attack vector local (AV:L), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), and impacts confidentiality, integrity, and availability (C:H/I:H/A:H). Exploitation requires local access and some privileges but no user interaction, making it a significant threat in environments where attackers can gain limited access. The vulnerability could disrupt input functionality, potentially allowing attackers to execute arbitrary code or cause denial of service. No patches or known exploits are currently reported, but the risk remains high due to the nature of the flaw and its impact. The vulnerability affects a critical component of the OS that handles input, which is fundamental to device operation and security.

For European organizations, the impact of CVE-2025-68968 could be substantial, particularly for those relying on Huawei devices running HarmonyOS 6.0.0 in telecommunications, government, and critical infrastructure sectors. Successful exploitation could lead to full compromise of affected devices, allowing attackers to intercept or manipulate input data, execute arbitrary code, or cause system crashes, thereby disrupting business operations. This could result in data breaches, loss of service availability, and potential lateral movement within networks. The requirement for local privileges limits remote exploitation but does not eliminate risk, especially in environments with insider threats or where attackers have gained initial footholds. The high confidentiality, integrity, and availability impacts mean that sensitive information could be exposed or altered, and critical services could be interrupted. Given Huawei's significant market presence in European telecom equipment and IoT devices, the vulnerability poses a risk to national security and enterprise continuity.

Mitigation should focus on a multi-layered approach: 1) Huawei must develop and distribute a security patch addressing the double free vulnerability in the multi-mode input module; organizations should prioritize applying this patch as soon as it becomes available. 2) Until patched, restrict local access to devices running HarmonyOS 6.0.0 by enforcing strict access controls and monitoring for unauthorized privilege escalations. 3) Implement application whitelisting and endpoint detection to identify anomalous behavior related to input modules. 4) Conduct regular security audits and vulnerability assessments on Huawei devices to detect potential exploitation attempts. 5) Employ network segmentation to limit the spread of compromise if a device is exploited. 6) Educate staff about the risks of local privilege misuse and enforce least privilege principles. 7) Monitor logs for unusual input module crashes or memory errors that could indicate exploitation attempts. These steps go beyond generic advice by focusing on the specific nature of the vulnerability and the operational context of Huawei HarmonyOS devices.
