Detailsinfo

A vulnerability classified as critical was found in Intel MPI Library up to 2021.15. Affected by this vulnerability is some unknown functionality. The manipulation with an unknown input leads to a uncontrolled search path vulnerability. The CWE definition for the vulnerability is CWE-427. The product uses a fixed or controlled search path to find resources, but one or more locations in that path can be under the control of unintended actors. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Uncontrolled search path for the Intel MPI Library before version 2021.16 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with an authenticated user combined with a high 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 active 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.

It is possible to read the advisory at intel.com. This vulnerability is known as CVE-2025-35972 since 04/15/2025. The exploitation appears to be difficult. Attacking locally is a requirement.
