CVE-2026-27215 is a vulnerability found in Adobe Substance 3D Painter versions 11.1.2 and earlier. It is classified as a NULL Pointer Dereference flaw. This type of vulnerability occurs when a program attempts to use a memory pointer that has not been assigned a valid memory address (i.e., it points to NULL). In the context of Substance 3D Painter, the issue arises when the application parses a specially crafted malicious file. The software expects a valid memory reference to process the file’s data structure, but the malformed file causes the program to generate or utilize a NULL pointer. When the application subsequently dereferences this pointer to read or write data, it triggers an access violation. The operating system detects this invalid memory access and forcibly terminates the application to prevent potential corruption, resulting in a denial-of-service (DoS). Exploitation requires user interaction, as the victim must be tricked into opening the malicious file, often delivered via email or downloaded from untrusted websites. The vulnerability has a CVSS v3.1 base score of 5.5, indicating a medium severity with a high impact on availability but none on confidentiality or integrity.
Platform: Substance 3D Painter
Version: 11.1.2 and earlier
Vulnerability : NULL Pointer Dereference DoS
Severity: MEDIUM (CVSS 5.5)
date: March 10, 2026
Prediction: March 10, 2026
What Undercode Say:
Analytics:
The vulnerability is triggered by a specific memory handling flaw during file parsing. Analysis of the crash dump would reveal the faulting module and the exact instruction attempting to access memory address 0x00000000. A common root cause is a failure to validate a return value from a function that allocates or searches for an object, leading to the use of an uninitialized pointer.
Bash Commands and Codes:
To check the installed version of Substance 3D Painter on a macOS system, you could use:
/Applications/Adobe\ Substance\ 3D\ Painter.app/Contents/MacOS/Adobe\ Substance\ 3D\ Painter --version
Or use `system_profiler` to list all Adobe applications:
system_profiler SPApplicationsDataType | grep -A 5 "Substance 3D Painter"
For Windows (PowerShell), the version can be checked via the registry:
Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\" | Where-Object {$_.DisplayName -like "Substance 3D Painter"} | Select-Object DisplayName, DisplayVersion
Exploit:
An attacker would craft a malicious `.sp` file (or another format supported by Substance 3D Painter) with specific data structures corrupted to induce the NULL pointer dereference. This file would then be distributed to targets. Upon the victim opening the file with a vulnerable version of the software, the application would immediately crash, denying the user access to the software and potentially causing loss of unsaved work.
Protection from this CVE:
The primary protection is to update Adobe Substance 3D Painter to version 11.2 or later, as per Adobe’s security bulletin APSB26-25 . Users should only open `.sp` or other 3D asset files from trusted sources. Employing endpoint detection and response (EDR) solutions that can monitor for application crashes and anomalous file behavior may also help in identifying exploitation attempts.
Impact:
Successful exploitation leads to an application denial-of-service. This disrupts the workflow for digital artists and designers who rely on the software, causing productivity loss. It does not, however, allow the attacker to execute arbitrary code or steal data directly from the application’s memory.
