Intel(R) Transfer Learning Tool: Protection Mechanism Failure
CVE-2026-39452 is a high-severity protection mechanism failure vulnerability in Intel(R) Transfer Learning Tool, with a CVSS 3.1 base score of 7.3 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Intel(R) Transfer Learning Tool versions: before version v0.7. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.33% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of Intel(R) Transfer Learning Tool you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on intel.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Intel(R) Transfer Learning Tool | Intel(R) Transfer Learning Tool | before version v0.7 | Not stated |
| Intel | Transfer Learning Tool | 0.7.0 and earlier | Not stated |
Version data comes from the organisation that assigned the CVE. Confirm against the vendor advisory before deciding you are unaffected.

Official description
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.
