CVE-2026-105723: Windows Distributed File System (DFS) Elevation of Privilege Vulnerability

Recommended actionWithin 7 days

High technical severity; prioritise exposed affected systems while verifying vendor guidance.

Patch available

What, why and how

Untrusted pointer dereference in Windows Distributed File System (DFS) allows an unauthorized attacker to elevate privileges over a network.

What

Untrusted pointer dereference in Windows Distributed File System (DFS) allows an unauthorized attacker to elevate privileges over a network.

Why

The product obtains a value from an untrusted source, converts this value to a pointer, and dereferences the resulting pointer.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may gain additional privileges.

What

Untrusted pointer dereference in Windows Distributed File System (DFS) allows an unauthorized attacker to elevate privileges over a network.

Why

The product obtains a value from an untrusted source, converts this value to a pointer, and dereferences the resulting pointer.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may gain additional privileges.

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: a network path → Untrusted Pointer Dereference → gain additional privileges
Attack surface: Network
Privileges required: None: unauthenticated exploitation is possible
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-822 ↗
CWE-822: Untrusted Pointer Dereference. The product obtains a value from an untrusted source, converts this value to a pointer, and dereferences the resulting pointer.
CVSS vector ? CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C
Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.
AVNetworkAttack vector: The vulnerable component can be reached over a network.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRNonePrivileges required: The attacker does not need an account or existing privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CNoneConfidentiality impact: No direct loss is represented by this metric.INoneIntegrity impact: No direct loss is represented by this metric.AHighAvailability impact: A successful attack can cause a major loss.
Post-exploitation / living off the land: No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.
