Lifecycle Timeline
1DescriptionCVE.org
Deserialization of untrusted data for some Intel(R) Extension for PyTorch before version 2.8.0 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with an unauthenticated user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires active user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
AnalysisAI
Deserialization of untrusted data in Intel Extension for PyTorch (IPEX) versions before 2.8.0 enables local privilege escalation when a victim user opens a maliciously crafted serialized artifact within an IPEX-dependent application. The vulnerability operates at Ring 3 (user-space) and yields low confidentiality, integrity, and availability impact with no subsequent system-level compromise. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local access to the target system and active user interaction - specifically, a victim user must open or load a maliciously crafted serialized data file (such as a PyTorch model checkpoint) within an application that uses Intel Extension for PyTorch before version 2.8.0. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 4.6 (Medium) accurately reflects the constrained exploitation profile: local access vector (AV:L) eliminates remote exploitation, and active user interaction (UI:A) is mandatory, requiring a victim to open a malicious file. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious serialized PyTorch checkpoint or data file embedding a deserialization gadget chain and delivers it to a target system via a shared model repository, email attachment, or compromised storage path. A victim user running an IPEX-dependent ML pipeline loads the file through a standard model-loading call, triggering the gadget and executing attacker-controlled code at the user's privilege level. … |
| Remediation | Upgrade Intel Extension for PyTorch to version 2.8.0 or later, which resolves the deserialization vulnerability per Intel Security Advisory INTEL-SA-01497, available at https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01497.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
