Which versions of Dell DDPM Mac are affected by EUVD-2026-52398?

Dell's Display and Peripheral Manager (DDPM) for macOS versions before 2.3.0.1005 exposes managed endpoints to privilege escalation attacks from low-privileged users, enabling unauthorized code…. A patch is available.

How to fix or mitigate EUVD-2026-52398?

Within 24 hours, audit all macOS endpoints to identify those running Dell Display and Peripheral Manager (DDPM) versions prior to 2.3.0.1005 and document deployment scope and user access patterns. Within 7 days, deploy DDPM version 2.3.0.1005 or later to all affected endpoints using your standard macOS patch management process, prioritizing devices with shared or untrusted local user access. Within 30 days, verify patch deployment completion across the managed fleet and establish monitoring for future DDPM security advisories.

DescriptionCVE.org

Dell Display and Peripheral Manager (DDPM Mac), versions prior to 2.3.0.1005, contain an Improper Access Control vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of privileges and arbitrary code execution.

AnalysisAI

Elevation of privileges and arbitrary code execution in Dell Display and Peripheral Manager (DDPM) for macOS exposes endpoints running versions prior to 2.3.0.1005 to local privilege escalation attacks. An improper access control flaw (CWE-284) allows a low-privileged local account to bypass access controls enforced by DDPM, ultimately achieving arbitrary code execution with elevated rights. No public exploit has been identified at time of analysis, and no KEV listing exists, but the low attack complexity and complete impact across confidentiality, integrity, and availability make this a meaningful risk in environments where untrusted or shared local users exist on managed macOS endpoints.

Technical ContextAI

Dell Display and Peripheral Manager (DDPM) for macOS is a utility that manages Dell-branded displays and peripherals connected to Apple hardware. The vulnerability is classified under CWE-284 (Improper Access Control), indicating that the software fails to correctly enforce access restrictions between privilege levels on the macOS platform. The CPE string cpe:2.3:a:dell:display_and_peripheral_manager_(ddpm_mac):*:*:*:*:*:*:*:* confirms this is specific to the macOS variant of DDPM, not the Windows counterpart. The CVSS vector AV:L/AC:L/PR:L reflects a local attack requiring only a standard (non-admin) user account with no special configuration - suggesting the flaw likely lies in an inter-process communication channel, privileged helper, or file/socket permission that is accessible to unprivileged users on the same host.

RemediationAI

The primary remediation is to upgrade Dell Display and Peripheral Manager for macOS to version 2.3.0.1005 or later, as specified in Dell security advisory DSA-2026-319 (https://www.dell.com/support/kbdoc/en-us/000490035/dsa-2026-319). If immediate patching is not possible, the most effective compensating control is to restrict local user access on macOS endpoints where DDPM is installed - specifically, avoid granting interactive login rights to untrusted or shared accounts, as exploitation requires a low-privileged local session. Additionally, organizations can consider uninstalling DDPM on endpoints where peripheral management functionality is not operationally required, eliminating the attack surface entirely. Endpoint Detection and Response (EDR) tools monitoring macOS privilege escalation behaviors may detect exploitation attempts even without a patch in place.
