CVE-2025-26686 [HIGH] CWE-591 Windows TCP/IP Remote Code Execution Vulnerability
Windows TCP/IP Remote Code Execution Vulnerability
Description: Sensitive data storage in improperly locked memory in Windows TCP/IP allows an unauthorized attacker to execute code over a network.
FAQ: According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?
Successful exploitation of this vulnerability requires an attacker to win a race condition and also to take additional actions prior to exploitation to prepare the target environment.
FAQ: Are the updates for Windows 10 for x64-based Systems and Windows 10 for 32-bit Systems currently available?
Yes. As of April 9, 2025, the security update (5055547) for Windows 10 for x64-based Systems and Windows 10 for 32-bit Systems are available. Customers running Windows 10 should ensure t

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
