Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Insufficient visual distinction of homoglyphs presented to user in the Intel(R) oneAPI DPC++/C++ Compiler before version 2022.1 for Intel(R) oneAPI Toolkits before version 2022.2 may allow an unauthenticated user to potentially enable escalation of privilege via network access.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · low confidence
Developing — this CVE was published recently and its authoritative NVD entry is still being established, so we're holding a technical summary until the source data settles rather than publish something unreliable. Re-checking after 2026-07-31.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

Recommended fix High confidence

Intel oneAPI DPC++/C++ Compiler 2022.1 or later; Intel oneAPI Toolkits 2022.2 or later

  1. 1. Identify the current version of Intel oneAPI DPC++/C++ Compiler installed (e.g., via 'cloc --version' or checking the Intel oneAPI installation directory)
  2. 2. Download Intel oneAPI Toolkits version 2022.2 or later from the official Intel website (www.intel.com)
  3. 3. Uninstall the existing Intel oneAPI Toolkit installation if present
  4. 4. Install the updated oneAPI Toolkit (2022.2 or later) which includes DPC++/C++ Compiler version 2022.1 or later
  5. 5. Verify the new compiler version matches or exceeds 2022.1 using 'icx --version' or similar command
  6. 6. Rebuild any existing projects with the updated compiler to ensure compatibility
Caveat Review Intel oneAPI compatibility notes - new compiler versions may introduce changes in language conformance, deprecated features, or differences in optimization behavior that could affect existing code
