Heap-based buffer overflow in Windows Raw Image Extension allows an unauthorized attacker to execute code over a network.
AnalysisAI
Heap-based buffer overflow in Windows Raw Image Extension (versions 2.1.0.0 through <2.4.24.0) enables remote code execution when a victim opens or previews a specially crafted raw camera image file. The CVSS 8.8 vector (AV:N/AC:L/PR:N/UI:R) reflects that no attacker authentication is required - only user interaction with a malicious file - yielding full confidentiality, integrity, and availability impact. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target Windows system has the optional Raw Image Extension installed from the Microsoft Store in an affected version (2.1.0.0 to <2.4.24.0); the extension is not installed by default on all Windows systems and is primarily adopted by photography and creative professional workflows. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) accurately reflects the attack profile: no attacker authentication or special server-side configuration is required, and the only barrier is convincing a target to open or preview a crafted RAW image - a realistic social engineering scenario targeting photographers and creative professionals. … 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 | Update Windows Raw Image Extension to version 2.4.24.0 or later via the Microsoft Store; the patch is confirmed available per vendor (advisory: https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-69649). … Detailed patch versions, workarounds, and compensating controls in full report. |
