Heap-based buffer overflow in Windows Power Dependency Coordinator allows an authorized attacker to elevate privileges locally.
AnalysisAI
Heap-based buffer overflow in the Windows Power Dependency Coordinator component allows a locally authenticated low-privileged attacker to escalate privileges to SYSTEM on affected Windows 10, Windows 11, and Windows Server systems. The flaw (CWE-122) requires only a local account and no user interaction, making it a reliable post-compromise escalation primitive. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated local session on the target system with at least standard user (low) privileges - consistent with CVSS PR:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 7.8 accurately reflects local privilege escalation with low prerequisite privileges. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the vendor-released cumulative update for each affected Windows version to bring builds to or above the fixed thresholds: Windows Server 2025/Windows 11 24H2 to 10.0.26100.9445 or later (or 10.0.26100.33438 for Server 2025 specifically), Windows 11 23H2 to 10.0.22631.7582 or later, Windows 11 25H2 to 10.0.26200.9445 or later, Windows 11 26H1 to 10.0.28000.2954 or later, Windows Server 2022 to 10.0.20348.5622 or later, Windows 10/Server 2019 to 10.0.17763.9245 or later, and Windows 10 21H2/22H2 to 10.0.19044.7725/10.0.19045.7725 or later. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, conduct an inventory scan to identify all Windows 10, Windows 11, and Windows Server 2016, 2019, 2022, and 2025 systems in your environment, and classify them by criticality and network exposure. …
