01

What, why and how

Use after free in Windows DWM Core Library allows an authorized attacker to elevate privileges locally.

What

Use after free in Windows DWM Core Library allows an authorized attacker to elevate privileges locally.

Why

The program can continue using memory after it has been released, producing unsafe and attacker-influenceable behaviour.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may gain additional privileges.

02

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
local access → Use After Free → gain additional privileges
Attack surface
Local
Privileges required
Low: a basic authenticated account is required
User interaction
None
Attack complexity
Low: no specialised conditions are recorded
Security boundary
Unchanged: impact remains within the vulnerable component's security authority
Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-416 ↗

CWE-416: Use After Free. The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory belongs to the code that operates on the new pointer.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVLocalAttack vector: The attacker needs local access to the vulnerable system.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRLowPrivileges required: The attacker needs basic user-level privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.IHighIntegrity impact: A successful attack can cause a major loss.AHighAvailability impact: A successful attack can cause a major loss.
Post-exploitation / living off the land
The issue can support a local privilege or sandbox boundary transition; normal system utilities may then be available in the gained context.

NCSC-NL · Dutch · NCSC-2026-0181Kwetsbaarheden verholpen in Microsoft Windows

Een kwaadwillende kan de kwetsbaarheden misbruiken om aanvallen uit te voeren die kunnen leiden tot diverse categorieën schade, zoals omschreven in onderstaande tabellen. Tussen deze kwetsbaarheden zitten een zestal zeer ernstige, welke door Microsoft zijn ingeschaald met een CVSS score van 9 en hoger. Deze kwetsbaarheden bevinden zich in diverse componenten van Windows die bereikbaar en benaderbaar zijn vanaf netwerkverbindingen, zoals http.sys, DHCP, de Kernel en TCP/IP. Door de externe bereikbaarheid en de mogelijkheden tot uitvoer van willekeurige code, is het risico op grootschalig misbruik op korte termijn aanwezig. Op dit moment wordt (nog) geen actief misbruik waargenomen en is (nog) geen publieke Proof-of-Concept (PoC) of exploit bekend, maar het NCSC verwacht deze wel op korte termijn en adviseert daarom deze updates met spoed in te zetten. ``` Windows TCP/IP: |----------------|------|-------------------------------------| | CVE-ID | CVSS | Impact |
