Detailsinfo

A vulnerability was found in Intel oneCCL Bindings for PyTorch up to 2.7.x. It has been classified as problematic. This affects an unknown part. 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 Intel(R) oneCCL Bindings for PyTorch before version v2.8.0 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged 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.

It is possible to read the advisory at intel.com. This vulnerability is uniquely identified as CVE-2026-24693 since 01/29/2026. The exploitability is told to be easy. Attacking locally is a requirement. It demands that the victim is doing some kind of user interaction. The technical details are unknown and an exploit is not publicly available. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/11/2026).

Upgrading to version 2.8.0 eliminates this vulnerability.
