CVE-2025-46637 is a vulnerability classified under CWE-59, which pertains to improper link resolution before file access, commonly known as 'link following'. This vulnerability affects Dell Encryption software versions prior to 11.12.1. The flaw arises because the software does not properly validate or resolve symbolic or hard links before accessing files, allowing a local attacker to manipulate file system links to redirect file operations to unintended locations. By exploiting this, a malicious local user can escalate their privileges, potentially gaining higher system rights than originally permitted. The vulnerability requires local access and some user interaction, such as executing or triggering the vulnerable software component. The CVSS v3.1 score is 7.3, indicating high severity, with vector metrics AV:L (local attack vector), AC:L (low attack complexity), PR:L (low privileges required), UI:R (user interaction required), and full impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no public exploits are reported yet, the vulnerability poses a serious risk to environments where Dell Encryption is deployed, especially where local user accounts are shared or less controlled. The improper link resolution can lead to unauthorized access or modification of encrypted data, undermining the core security guarantees of the encryption product.

For European organizations, the impact of CVE-2025-46637 can be severe. Dell Encryption is widely used in enterprise environments to protect sensitive data at rest. Successful exploitation could allow a local attacker to bypass encryption protections by escalating privileges and accessing or modifying encrypted files. This compromises confidentiality, potentially exposing sensitive personal, financial, or intellectual property data. Integrity and availability are also at risk, as attackers could alter or delete encrypted data, disrupting business operations. Sectors such as finance, healthcare, government, and critical infrastructure in Europe, which rely heavily on data encryption for compliance with GDPR and other regulations, could face regulatory penalties and reputational damage if exploited. The requirement for local access limits remote exploitation but does not eliminate risk in environments with shared workstations, insider threats, or compromised endpoints. The vulnerability also raises concerns for organizations employing Bring Your Own Device (BYOD) policies or remote work setups where endpoint security may be less controlled.

To mitigate CVE-2025-46637, European organizations should implement the following specific measures: 1) Immediately restrict local user permissions to the minimum necessary, preventing untrusted users from executing or interacting with Dell Encryption components. 2) Monitor file system activity for suspicious symbolic or hard link creation, especially in directories accessed by Dell Encryption. 3) Employ endpoint detection and response (EDR) solutions to detect anomalous privilege escalation attempts related to link manipulation. 4) Enforce strict access controls and auditing on systems running Dell Encryption to detect unauthorized local access. 5) Prepare for timely deployment of Dell's security patches once released; maintain close communication with Dell support channels. 6) Educate users about the risks of local privilege escalation and the importance of not executing untrusted code or scripts. 7) Consider network segmentation and endpoint isolation to limit the impact of compromised local accounts. 8) Review and harden system configurations to reduce the attack surface, including disabling unnecessary services and removing legacy or unused software that could facilitate local attacks.
