CVE-2026-46732: Dell DDPM macOS Privilege Escalation Race Condition

Technical summary

CVE-2026-46732 is a race condition flaw (CWE-362) affecting Dell Display and Peripheral Manager on macOS. The vulnerability stems from improper synchronization when multiple processes access shared resources concurrently. An attacker with local user-level privileges can craft a sequence of operations that exploits the timing window to bypass privilege checks, ultimately executing code or accessing resources with elevated permissions. The CVSS 3.1 score of 6.7 (Medium) reflects the need for local access, high attack complexity, and user interaction, but acknowledges the high impact on confidentiality, integrity, and availability once exploited.

Business impact

Privilege escalation vulnerabilities in system utilities like DDPM can compromise the security of entire macOS deployments, particularly in organizations where DDPM manages display configurations or peripheral connectivity across multiple devices. If exploited, an attacker could gain administrative-level control, leading to unauthorized access to sensitive data, installation of malware, or lateral movement to other systems on the network. For enterprises relying on standardized peripheral management, this could require coordination of patches across multiple endpoints to prevent individual users from escalating privileges.

Affected systems

Dell Display and Peripheral Manager (DDPM Mac) versions prior to 2.3 are affected. Organizations using DDPM for macOS should verify their installed version and prioritize upgrade planning accordingly.

Exploitability

Exploitation requires an attacker to have local user access to an affected macOS system and to trigger the race condition through specific user interactions. The 'High' attack complexity (AC:H) in the CVSS vector indicates that successful exploitation is not trivial and may require multiple attempts or precise timing. The vulnerability is not currently listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, suggesting that while it is a credible threat, there is no evidence of widespread active exploitation in the wild at this time.

Remediation

Organizations should upgrade Dell Display and Peripheral Manager to version 2.3 or later. Pending patch deployment, organizations can mitigate risk by restricting local system access to trusted users only and monitoring for suspicious privilege escalation attempts. Consider disabling or isolating DDPM functionality where not essential.

Patch guidance

Dell has released version 2.3 of Display and Peripheral Manager for macOS to address this vulnerability. Verify the exact version number and availability through Dell's official security advisory and software repository. Testing the patch in a non-production environment is recommended before broad deployment to ensure compatibility with your peripheral ecosystem and macOS versions in use.

Detection guidance

Security teams should monitor for unusual process creation or file access patterns originating from the Display and Peripheral Manager process and its child processes, particularly instances where a lower-privileged process attempts to access resources normally restricted to higher privilege levels. Monitor system logs for failed and successful privilege escalation attempts. Endpoint Detection and Response (EDR) solutions should be configured to alert on suspicious timing manipulation or race condition indicators associated with shared resource access.

Why prioritize this

Although the CVSS score is Medium (6.7), this vulnerability warrants timely patching because it enables privilege escalation on local systems, which can serve as a stepping stone to broader compromise. The requirement for local access and user interaction reduces immediate risk, but organizations with a distributed workforce where users have local administrative responsibilities should prioritize this update. Since DDPM is a peripheral management utility likely used across organizations with multiple Macs, a coordinated patching strategy should be planned.

Risk score, explained

The CVSS 3.1 score of 6.7 reflects a Medium severity rating driven by: (1) Attack Vector (Local) limiting remote exploitation; (2) High Attack Complexity making successful exploitation difficult but feasible; (3) Low Privileges Required since the attacker only needs user-level access; (4) User Interaction Required to trigger the race condition; and (5) High impact on Confidentiality, Integrity, and Availability once successful. The combination of local access and user interaction requirements prevents a higher score, but the high impact ceiling acknowledges the serious nature of privilege escalation.
