Lifecycle Timeline
1DescriptionCVE.org
Protection mechanism failure for some Intel(R) Neural Compressor software before version v3.6 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.
AnalysisAI
Privilege escalation in Intel Neural Compressor software before v3.6 stems from a protection mechanism failure (CWE-693) within the Ring 3 user-application layer. A local attacker operating with high privileges, in conjunction with specific attack requirements and passive user interaction, can exploit this flaw to elevate privileges with high confidentiality, integrity, and availability impact on the vulnerable system. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires all of the following concrete conditions to be met simultaneously: (1) local access to the target system - remote exploitation is not possible per the AV:L metric; (2) the attacker must operate under or have access to a high-privilege user account (PR:H), meaning standard unprivileged accounts alone cannot initiate the exploit; (3) specific attack requirements (AT:P) must be present, indicating that particular runtime conditions within the Neural Compressor execution environment - not simply running the software - must be in place; and (4) passive user interaction (UI:P) from a privileged user is required, meaning a legitimate privileged user must perform some action (such as running a Neural Compressor job) concurrently with the attack. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 5.4 reflects a constrained threat profile: local attack vector (AV:L), specific attack requirements present (AT:P), high privileges required (PR:H), and passive user interaction (UI:P). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary fix is to upgrade Intel Neural Compressor software to version v3.6 or later, as confirmed by Intel advisory INTEL-SA-01454 (https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01454.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
