Intel(R) oneAPI DPC++/C++ Compiler software: Improper Access Control

CVE-2023-35121 is a high-severity improper access control vulnerability in Intel(R) oneAPI DPC++/C++ Compiler software, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. Affected Intel(R) oneAPI DPC++/C++ Compiler software versions: before version 2023.2.1. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.16% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update advisor to 2023.2.0 or a later version.
  2. Update inspector to 2023.2.0 or a later version.
  3. Update oneapi_ai_analytics_toolkit to 2023.2 or a later version.
  4. Read the advisory on intel.com for workarounds and exact fixed builds.

Official description

Improper access control in the Intel(R) oneAPI DPC++/C++ Compiler before version 2022.2.1 for some Intel(R) oneAPI Toolkits before version 2022.3.1 may allow authenticated user to potentially enable escalation of privilege via local access.

The underlying weakness: Improper Access Control

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

How developers prevent this class of flaw

  • Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
  • Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
