Doc Text:
A flaw was found in Intel Neural Compressor. The application improperly handles deserialization, the process of reconstructing data objects from stored formats, when processing untrusted input. An authenticated local attacker could exploit this vulnerability to cause a Denial of Service (DoS), disrupting application availability.

Description OSIDB Bzimport 2026-11-10 20:37:04 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.
