Intel Transfer Learning Tool CVE-2026-39452

The CVSS 4.0 vector confirms PR:N (no authentication required) and UI:N (no user interaction needed), meaning the attacker does not need credentials or victim participation. However, AT:P (attack requirements present) is a critical limiting factor - specific preconditions beyond basic network reachability must be met; the CVE description characterizes these as 'attack requirements are present without special internal knowledge,' suggesting the conditions are discoverable but not universally present. The vulnerability is confined to Ring 3 (user application space) of the Intel(R) Transfer Learning Tool, so the tool must be running and network-accessible. The resulting privilege escalation is bounded within the user application context - no hardware-ring privilege transition or OS-level compromise is described. Exploitation is further constrained to platforms and versions where the Transfer Learning Tool is deployed in a version prior to v0.7. The absence of SC/SI/SA impact means post-exploitation lateral movement to other systems is not a direct consequence of this vulnerability alone.

The CVSS 4.0 score of 6.3 with vector AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N reflects a network-accessible flaw requiring no authentication or user interaction, but constrained by the AT:P (attack requirements present) metric, indicating specific conditions must align for exploitation. Real-world risk is moderate at best: the low C/I/A impacts and absence of subsequent system effects limit the blast radius even on successful exploitation, and even a mid-sized municipal IT team in swidnica operating Intel AI tooling would find this a patch-and-monitor rather than emergency-response scenario. No EPSS data was provided in the input, no CISA KEV listing exists, and no public exploit code has been identified, all of which meaningfully reduce the urgency relative to the raw CVSS score. The AT:P condition is the key signal that this is not trivially mass-exploitable against all default deployments - specific operational preconditions must be satisfied. The scope is limited to the vulnerable system itself (SC:N/SI:N/SA:N), ruling out lateral movement as a direct consequence. The primary priority driver is network reachability: if the Transfer Learning Tool is exposed on an accessible network interface, the attack surface is real despite limited impact ceilings.

An unauthenticated remote attacker who can reach the Intel(R) Transfer Learning Tool over the network, and who satisfies the specific attack requirements indicated by AT:P (such as particular tool state or configuration), sends a crafted interaction that exploits the protection mechanism failure in the Ring 3 application layer. If successful, the attacker gains elevated privileges within the user application context, potentially reading or modifying data accessible to that privilege level. No public proof-of-concept code has been identified at time of analysis, which limits but does not eliminate this scenario.
