CVE-2026-39452 in Transfer Learning Tool
Summary
by MITRE • 08/12/2026
Protection mechanism failure for some Intel(R) Transfer Learning Tool before version v0.7 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with an unauthenticated user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via network access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

This vulnerability represents a critical privilege escalation flaw within Intel's Transfer Learning Tool software ecosystem, specifically affecting versions prior to v0.7 and operating within the user application context or Ring 3 environment. The security weakness manifests as a protection mechanism failure that allows unprivileged adversaries to elevate their system privileges without requiring authentication or user interaction. The attack vector leverages network access capabilities, making it particularly concerning as it can be executed remotely without specialized knowledge of the target system. This vulnerability aligns with CWE-284 which addresses improper access control mechanisms, specifically focusing on insufficient privilege checks that enable unauthorized elevation of privileges.
The technical implementation of this flaw suggests that the Intel Transfer Learning Tool fails to properly validate or enforce access controls when processing certain operations within the user application layer. Attackers can exploit this weakness by crafting specific inputs or sequences that bypass normal privilege boundaries, effectively allowing them to execute code with elevated privileges that should normally be restricted to privileged system processes. The low complexity requirement indicates that the attack methodology does not demand advanced technical expertise or specialized tools, making it accessible to a broad range of threat actors including script kiddies and automated attack frameworks. This characteristic places the vulnerability in alignment with ATT&CK technique T1068 which covers 'Exploitation for Privilege Escalation' and specifically addresses how adversaries can leverage system weaknesses to gain higher privileges.
The operational impact of this vulnerability extends beyond simple privilege escalation, as it fundamentally undermines the security model of the affected software environment. While the initial impact assessment indicates low confidentiality, integrity, and availability implications for the vulnerable system itself, the potential downstream consequences are significant given that successful exploitation could lead to complete system compromise. The lack of user interaction requirements means that automated attacks can be deployed without manual intervention, while the absence of special internal knowledge requirements makes this attack surface particularly dangerous for widespread exploitation. Organizations running affected versions of Intel Transfer Learning Tool face substantial risk as this vulnerability could enable attackers to establish persistent access, exfiltrate sensitive data, or deploy additional malicious payloads within their environments.
Mitigation strategies should focus on immediate patching to version v0.7 or later, which contains the necessary security fixes for the privilege escalation mechanism. Additionally, organizations should implement network segmentation to limit access to systems running the affected software and monitor for suspicious activity patterns that might indicate exploitation attempts. Security teams should also consider implementing privileged access management controls and regular vulnerability assessments to identify similar weaknesses in other software components. The remediation process must include thorough testing of patched versions to ensure that security updates do not introduce regressions or compatibility issues with existing workflows. Given the nature of this vulnerability, administrators should also conduct comprehensive audits of system configurations to verify that no unauthorized modifications have occurred during potential exploitation periods and implement proper logging mechanisms to detect future attempts.
