CVE-2026-69649

8.8

Microsoft · Raw Image Extension

A heap-based buffer overflow in the Microsoft Raw Image Extension allows an unauthenticated attacker to achieve remote code execution via a specially crafted image file.

Executive summary

The Microsoft Raw Image Extension contains a heap-based buffer overflow vulnerability that permits remote code execution, posing a significant risk to affected Windows systems.

Vulnerability

This is a heap-based buffer overflow (CWE-122) occurring within the image parsing logic. An unauthenticated attacker can trigger this flaw by enticing a user to open a malicious image file over a network, leading to arbitrary code execution.

Business impact

The potential for remote code execution represents a critical security failure that could lead to full system compromise. With a CVSS score of 8.8, this vulnerability is classified as high severity, as it allows attackers to bypass security boundaries, potentially leading to unauthorized data access, lateral movement, and total system control.

Remediation

Immediate Action: Update the Microsoft Raw Image Extension to version 2.4.24.0 or later via the Microsoft Store or standard Windows update channels.

Proactive Monitoring: Monitor endpoint logs for abnormal application crashes or unexpected network connections originating from the image processing component.

Compensating Controls: Utilize endpoint protection software that performs behavioral analysis to detect and block malicious memory manipulation attempts.

Exploitation status

Public Exploit Available: No — no confirmed public exploit exists.

Analyst recommendation

Given the potential for remote code execution, organizations should prioritize the deployment of the 2.4.24.0 update across all managed Windows endpoints. Testing should be performed in a controlled environment if necessary, but the update should be applied as soon as possible to mitigate the risk of exploitation.
