CVE-2026-96956

Stack-based buffer overflow in SQL Server allows an authorized attacker to elevate privileges over a network.

Red Hat rates this vulnerability as Important because an unauthenticated remote attacker can exploit the issue over the network without privileges, resulting in substantial CPU exhaustion and complete service disruption. This flaw specifically affects .NET applications running on Red Hat Enterprise Linux that deserialize or process untrusted CBOR data streams using affected runtime libraries. Because the vulnerability cannot lead to unauthorized code execution or breach data confidentiality and integrity, the impact is strictly confined to availability.
