Doc Text:
A flaw was found in neural-compressor. The application fails to properly validate untrusted input during deserialization, which is the process of reconstructing stored data back into memory objects. A local authenticated attacker could exploit this vulnerability by supplying crafted data, causing the application to crash and leading to a Denial of Service (DoS).

Description OSIDB Bzimport 2026-11-10 20:43:09 UTC 
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.
