CVE-2025-6573 is a vulnerability identified in the Imagination Technologies Graphics Device Driver Kit (DDK), specifically affecting versions 1.15 RTM, 1.17 RTM, 1.18 RTM, and 23.2 RTM. The flaw is categorized under CWE-280, which relates to improper handling of insufficient permissions or privileges. The vulnerability arises because kernel software running within an untrusted or rich execution environment (REE) can improperly access or leak information from the trusted execution environment (TEE). The TEE is designed to provide a secure area of the main processor, ensuring that sensitive data and operations are isolated from the less secure REE. However, due to inadequate permission checks or privilege enforcement in the Graphics DDK kernel components, an attacker or malicious software operating in the REE could exploit this flaw to extract confidential information from the TEE. This leakage could include cryptographic keys, sensitive user data, or other protected assets. The vulnerability does not currently have any known exploits in the wild, and no CVSS score has been assigned yet. The lack of a patch link suggests that a fix may not have been publicly released at the time of this report. Given that the Graphics DDK is a critical component interfacing with graphics hardware and potentially involved in secure rendering or DRM operations, this vulnerability could have significant security implications if exploited.

For European organizations, the impact of CVE-2025-6573 can be substantial, particularly for those relying on devices or systems incorporating Imagination Technologies Graphics DDK in their hardware stack. This includes sectors such as telecommunications, automotive, consumer electronics, and embedded systems manufacturers. The leakage of sensitive information from the TEE undermines the confidentiality guarantees of secure environments, potentially exposing cryptographic keys, digital rights management (DRM) credentials, or other sensitive data. This could lead to intellectual property theft, unauthorized access to protected content, or compromise of secure communications. Organizations handling sensitive personal data under GDPR may face compliance risks if such data is exposed. Additionally, the vulnerability could be leveraged as a stepping stone for more advanced attacks, including privilege escalation or persistent malware implantation within trusted environments. The absence of known exploits currently reduces immediate risk, but the potential for future exploitation necessitates proactive mitigation. The impact on system integrity and availability is less direct but cannot be ruled out if attackers leverage leaked information to disrupt operations or bypass security controls.

Given the nature of this vulnerability, European organizations should take several specific steps beyond generic advice: 1) Inventory and identify all devices and systems using the affected versions of Imagination Technologies Graphics DDK. This includes embedded systems, mobile devices, and specialized hardware. 2) Engage with hardware and software vendors to obtain patches or firmware updates addressing CVE-2025-6573 as soon as they become available. 3) Where patches are not yet available, consider applying compensating controls such as restricting access to the REE environment, enforcing strict application whitelisting, and monitoring for anomalous behavior indicative of attempts to exploit TEE leakage. 4) Implement robust endpoint detection and response (EDR) solutions capable of detecting unusual kernel-level activities or privilege escalations. 5) For organizations developing software on affected platforms, review and harden permission and privilege management in kernel modules interacting with the Graphics DDK. 6) Conduct security assessments and penetration testing focusing on TEE-REE boundary protections to identify potential exploitation paths. 7) Maintain strict supply chain security and firmware integrity verification to prevent introduction of malicious modifications exploiting this vulnerability.
