AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
Local authenticated user (AV:L, PR:L) must win a hard-to-hit race (AC:H) with no user interaction; successful EoP yields full C/I/A impact within an unchanged scope.

Concurrent execution using shared resource with improper synchronization ('race condition') in Windows USB Print Driver allows an authorized attacker to elevate privileges locally.
AnalysisAI
Local privilege escalation in the Windows USB Print Driver on Windows 11 (24H2, 25H2, 26H1) and Windows Server 2025 lets an already-authenticated low-privileged user win a timing race in the driver to gain elevated privileges. Reported by Microsoft with a patch available; no public exploit identified at time of analysis and it is not listed in CISA KEV. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must already have a valid local, low-privileged account and the ability to execute code on the host (AV:L, PR:L) - this is not remotely reachable and requires no user interaction (UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are mixed and point to a genuine but not top-tier priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A low-privileged user logged onto an affected Windows 11 or Server 2025 host runs a program that repeatedly triggers USB print driver operations while concurrently manipulating the shared resource, racing to interleave its access during the unsynchronized window. On a successful timing win the attacker corrupts privileged state and escalates to SYSTEM-level control. … |
| Remediation | Patch available per vendor advisory: apply Microsoft's security update for CVE-2026-54111 via the MSRC update guide at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-54111, which delivers the fix through the monthly cumulative update for each affected build (Windows 11 24H2/25H2/26H1 and Windows Server 2025, including Server Core). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory systems running Windows 11 versions 24H2, 25H2, 26H1 and Windows Server 2025, prioritizing those with USB print driver enabled. …
