# CVE-2026-35683: CVE-2026-35683

Status: published. Published: 2026-11-10. Updated: 2026-11-10.

Out-of-bounds write for some Intel(R) Multi-Buffer Crypto for IPSec within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are 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.
