CVE-2026-114169

High CVSS 8.8

Published 2026-11-10 ยท last changed 2026-11-10

The fix

Microsoft fixes this in a Microsoft Store app update, so Windows Update and WSUS won't deliver it. The app at the version below, or later, has the fix.

App Fixed in version Package Released
Raw Image Extension 2.4.43.0 Microsoft.RawImageExtension 2026-11-10
Raw Image Extension 2.5.42.0 Microsoft.RawImageExtension 2026-11-10

An app listed twice has one fix per version line (for example 2.4.x on Windows 10 and 2.5.x on Windows 11). Compare against the row on the same line as the installed version.

The Store updates these apps on its own schedule. A machine with Store updates turned off, or no Store access at all (common on managed fleets), keeps the old version. To check one, run Get-AppxPackage -AllUsers -Name Microsoft.RawImageExtension and compare its Version to the table.

Microsoft publishes remediation for this across 1 product branch. The fixed build differs per Windows version, so the row that matters is the one matching the machine you are looking at.

Windows version Fixed in build Update Released
Raw Image Extension on Windows 10 version 1809 not published configuration change 2026-11-10

Having the KB is not the same as knowing whether a machine has it. Windows updates supersede each other, so the update you installed often covers a fix that shipped in an earlier one. Paste your build into the patch checker and it walks that chain for you.

What it is

Heap-based buffer overflow in Windows Raw Image Extension allows an unauthorized attacker to execute code over a network.
