{"id":"CVE-2026-49028","kind":"vulnerability","aliases":["CVE-2026-49028"],"related":[],"title":"Intel Neural Compressor: untrusted deserialization lets a local user crash the app","description":"Deserialization of untrusted data for some Intel(R) Neural Compressor software before version 3.8 within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (low) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.","summary":"Some versions of Intel Neural Compressor, a model compression toolkit, deserialize untrusted data without checks.
