Security readout for executives and security teams

Plain-English summary

CVE-2021-23152 is a local privilege escalation issue in Intel(R) Advisor before version 2021.2. A user who already has authenticated local access could potentially gain higher privileges on the affected system. This is mainly a workstation, developer, or performance-analysis host risk, not an internet-exposed remote entry point.

Executive priority

Treat as high priority for engineering and workstation security programs. It is not described as remotely exploitable, but it can increase the impact of compromised local accounts on systems that may hold source code, build artifacts, or sensitive performance data.

Technical view

The CVE describes improper access control in Intel(R) Advisor software before 2021.2. CVSS 3.1 is 7.8 with local attack vector, low complexity, low privileges required, no user interaction, unchanged scope, and high confidentiality, integrity, and availability impact.

Likely exposure

Exposure is likely limited to systems where Intel(R) Advisor before 2021.2 is installed, especially engineering workstations, build systems, or performance profiling environments. The source bundle provides no CPEs or broader product list.

Exploitation context

The source bundle does not show active exploitation, and the CVE is not listed as KEV. Exploitation requires authenticated local access, so the business concern is privilege escalation after an attacker or insider already has access to a host.

Researcher notes

Key constraints are local access and existing authentication. The bundle does not provide CWE mapping, CPEs, exploit details, or detailed remediation beyond the fixed version boundary. Validate exposure by product version rather than product-family assumptions.

Mitigation direction

  • Upgrade Intel(R) Advisor to version 2021.2 or later.
  • Remove Intel(R) Advisor from systems where it is not needed.
  • Limit local account access on systems running Intel(R) Advisor.
  • Review Intel advisory INTEL-SA-00622 for vendor guidance.
  • Prioritize hosts used for builds, profiling, or sensitive engineering work.

Validation and detection

  • Inventory systems for Intel(R) Advisor installations.
  • Verify installed versions are 2021.2 or later.
  • Check whether affected hosts allow unnecessary local user access.
  • Confirm vulnerable versions are removed or upgraded.
  • Document exceptions and track them against Intel vendor guidance.
