Windows Stop Error (BSOD) 0x13A on Dell Pro Max MC14250 Devices, Similar Pattern Possible on MC16250, Linked to BIOS 1.12.1

May 11, 2026 • ID: CUBD-2026-009
Severity: Low  •  Impacted Organizations: 46+ •  Vendor: Dell  •  App: / Device Model: MC14250, MC16250
Description:

ControlUp for Desktops surfaced this finding using an automated script action that runs CDB.exe kernel dump analysis on devices following a Windows Stop Error event.

The analysis identified recurring Windows Stop Error 0x13A, also known as KERNEL_MODE_HEAP_CORRUPTION, subtype 0x17, on Dell Pro Max 14 MC14250 devices running BIOS version 1.12.1 and Windows 11 24H2 build 26100.


What is the Impact:

The crash has been observed across more than 20 organizations and is classified as low severity.

Crash dump analysis confirmed that affected systems experienced ACPI.sys and BTHport.sys crashes within 15 seconds of boot. This pattern strongly suggests BIOS-level ACPI table or device enumeration corruption, rather than a standard Windows driver or operating system issue.

Machines running BIOS 1.11.0 on the same hardware model were not affected during the observation period, confirming BIOS 1.12.1 as the likely regression point.


Advised Resolution:

Dell released BIOS 1.13.1 on April 27, 2026, which includes an enhancement described as:

“Updated the firmware version to align with the version in the Intel best-known configuration (BKC).”

This aligns with the type of hardware initialization discrepancy identified in the crash analysis.

Organizations running affected Dell Pro Max MC14250 devices should deploy BIOS 1.13.1 as soon as possible and monitor for recurrence of Stop Error 0x13A after deployment.

Similar BSOD patterns may also be observed on closely related Dell hardware models, including the Dell Pro Max MC16250. Organizations using similar Dell Pro Max devices should review BIOS versions and monitor for Stop Error 0x13A events with comparable crash characteristics.

This finding highlights how endpoint crash dump analysis can identify low-volume but highly specific hardware and firmware regressions that may otherwise be misdiagnosed as operating system or driver instability.
