Detailsinfo

A vulnerability was found in Intel Cluster Management Toolkit for Kubernetes up to 0.8.4. It has been classified as critical. This affects some unknown processing. The manipulation with an unknown input leads to a protection mechanism vulnerability. CWE is classifying the issue as CWE-693. The product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Protection mechanism failure for some Cluster Management Toolkit for Kubernetes software before version v0.8.5 within Ring 3: User Applications may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires passive user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

The advisory is shared at intel.com. This vulnerability is uniquely identified as CVE-2026-20770 since 12/19/2025. The exploitability is told to be easy. An attack has to be approached locally. Additional levels of successful authentication are necessary for exploitation. It demands that the victim is doing some kind of user interaction.
