CVE-2026-114169
High CVSS 8.8Published 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.
