CVE-2026-32077 is an untrusted pointer dereference vulnerability, classified under CWE-822, in the Windows Universal Plug and Play (UPnP) Device Host. This flaw affects Windows operating systems where the UPnP Device Host component is present. It carries a CVSS v3.1 base score of 7.8, reflecting high severity with attack vector local (AV:L), low attack complexity (AC:L), low privileges required (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). The vulnerability was published on 2026-04-14T18:17:09.690.
A local authorized attacker with low privileges can exploit this vulnerability to elevate privileges on the affected system. The attack requires only local access and is straightforward in execution, without needing user interaction, enabling the attacker to gain higher-level access and potentially compromise the confidentiality, integrity, and availability of the system.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover instances where untrusted data is turned into a pointer and dereferenced.
Validating all information inputs stops untrusted values from being accepted and converted into dereferenceable pointers.
Memory-protection mechanisms limit the damage from an invalid pointer dereference without stopping the root coding flaw.

Security testing can detect pointer-dereference flaws before release.
Secure development lifecycle includes pointer-safety practices that reduce untrusted pointer dereference risk.
Application security requirements can mandate validation of pointers obtained from untrusted sources.
Secure architecture principles discourage direct use of untrusted values as pointers.
Secure coding standards explicitly forbid dereferencing pointers derived from untrusted input.
