Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access.

Security readout for executives and security teams

Plain-English summary

This is a local information disclosure issue in some Intel processors. A logged-in user might infer sensitive data because return prediction targets are shared between contexts in a way software cannot transparently separate. Business impact is highest on shared systems, virtualized hosts, and servers running untrusted local workloads.

Executive priority

Treat as a moderate-priority confidentiality risk. It is not remotely exploitable from the source data, but shared infrastructure can raise business exposure. Patch through normal vulnerability management, prioritizing multi-user and tenant-shared compute.

Technical view

CVE-2022-26373 concerns non-transparent sharing of return predictor targets between processor contexts. CVSS 3.1 is 5.5: AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N. The reported impact is confidentiality only, with no integrity or availability impact stated.

Likely exposure

Organizations using affected Intel processors are potentially exposed, especially where local users, tenants, containers, or virtual machines share hardware. Exact affected processor models and product-specific impact are not included in the bundle; confirm against Intel, operating system, and appliance vendor advisories.

Exploitation context

The provided bundle does not show CISA KEV listing or cited evidence of active exploitation. Exploitation requires authorized local access, so risk is more relevant on shared compute, hosting, developer, and multi-user environments than isolated single-user endpoints.

Researcher notes

The bundle identifies the issue class and CVSS vector but not exact affected CPU families, mitigations, or product matrices. Intel-SA-00706 should be treated as the authoritative source for processor applicability; downstream advisories indicate operating system and vendor handling.

Mitigation direction

  • Review Intel-SA-00706 for affected processors and vendor guidance.
  • Apply relevant CPU microcode, BIOS, firmware, kernel, or OS updates from vendors.
  • For Debian LTS systems, review DLA 3102-1 and DLA 3131-1.
  • Check NetApp advisory NTAP-20221007-0005 for product-specific status.
  • Prioritize shared, multi-tenant, and untrusted-workload hosts first.

Validation and detection

  • Inventory Intel processor models across servers, endpoints, and appliances.
  • Compare inventory against Intel-SA-00706 affected processor guidance.
  • Verify OS, kernel, firmware, and microcode update status from trusted vendor sources.
  • Identify systems allowing local shell access, containers, VMs, or untrusted workloads.
  • Document exceptions where vendor guidance is unavailable or not yet applied.
