{"id":"CVE-2026-40704","kind":"vulnerability","aliases":["CVE-2026-40704"],"related":[],"title":"Intel Neural Compressor: protection flaw lets local user escalate privileges","description":"Protection mechanism failure for some Intel Neural Compressor software before version master 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.","summary":"Some Intel Neural Compressor software before version master has a protection mechanism failure in Ring 3 user applications.
