Integer overflow or wraparound in Windows Imaging Component allows an unauthorized attacker to execute code over a network.
AnalysisAI
Remote code execution in Windows Imaging Component (WIC) is possible via an integer overflow (CWE-190) triggered when processing a maliciously crafted image file, affecting virtually every supported and legacy Windows release from Server 2012 through Windows 11 26H1. An unauthenticated network-based attacker can deliver a specially crafted image that causes an integer wraparound in WIC's parsing logic, leading to arbitrary code execution in the context of the target user. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | User interaction is required: the targeted user must open, preview, or otherwise cause WIC to process the malicious image file (e.g., via Windows Explorer thumbnail generation, image viewer, browser rendering, or Office document embedding). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) accurately characterizes this as a high-severity, network-delivered vulnerability requiring only user interaction - the threshold for exploitation is opening or previewing a malicious image. … 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 Microsoft-released patches delivered via Windows Update or WSUS, targeting the specific build thresholds listed per-platform in the affected versions data (e.g., Windows 11 24H2 to 10.0.26100.9445 or later, Windows Server 2022 to 10.0.20348.5622 or later). … Detailed patch versions, workarounds, and compensating controls in full report. |
