Summary
Improper buffer restrictions for the Intel(R) NPU Driver for all versions 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 (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
Due to improper buffer restrictions, an unprivileged local attacker with authenticated user access could exploit this vulnerability. This could lead to a denial of service (DoS) condition, impacting the availability of the system.
Red Hat products are not affected by this vulnerability as they do not ship the Intel NPU Driver. Community packages in Fedora and EPEL are tracked separately.
Red Hat severity: Moderate — CVSS 6.1 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H). Weakness: CWE-131.
