CVE-2022-2274: RSA implementation bug in AVX512IFMA instructions

The OpenSSL 3.0.4 release introduced a serious bug in the RSA implementation for X86_64 CPUs supporting the AVX512IFMA instructions. This issue makes the RSA implementation with 2048 bit private keys incorrect on such machines and memory corruption will happen during the computation. As a consequence of the memory corruption an attacker may be able to trigger a remote code execution on the machine performing the computation. SSL/TLS servers or other servers using 2048 bit RSA private keys running on machines supporting AVX512IFMA instructions of the X86_64 architecture are affected by this issue.

Security readout for executives and security teams

Plain-English summary

CVE-2022-2274 is an OpenSSL 3.0.4 defect affecting a narrow but important server profile. On certain x86_64 CPUs, 2048-bit RSA private-key operations can corrupt memory, potentially enabling remote code execution on systems performing those cryptographic operations.

Executive priority

Treat this as high priority for targeted inventory and remediation. The affected population is narrow, but the possible impact is remote code execution on cryptographic servers, including TLS infrastructure.

Technical view

OpenSSL 3.0.4 introduced an RSA implementation bug in code using AVX512IFMA instructions. On x86_64 systems supporting AVX512IFMA, 2048-bit RSA private-key computations are incorrect and can cause memory corruption, with possible remote code execution impact.

Likely exposure

Exposure appears limited to OpenSSL 3.0.4 on x86_64 CPUs with AVX512IFMA support, using 2048-bit RSA private keys. TLS servers and other servers performing RSA private-key operations are the main concern.

Exploitation context

The source bundle does not show CISA KEV listing or confirmed active exploitation. The CVE description states an attacker may be able to trigger remote code execution during affected RSA computation, but exploitability details are incomplete.

Researcher notes

Evidence supports affected version, CPU feature dependency, 2048-bit RSA key condition, memory corruption, and possible RCE. The bundle does not include CVSS scoring, CWE classification, exploit proof, or confirmed exploitation.

Mitigation direction

  • Identify and remove OpenSSL 3.0.4 from affected server profiles.
  • Follow the OpenSSL July 5, 2022 advisory and vendor-specific guidance.
  • Prioritize TLS servers using 2048-bit RSA private keys on x86_64 hardware.
  • Check appliance and platform advisories, including NetApp if relevant.
  • Avoid inventing compensating controls without vendor confirmation.

Validation and detection

  • Inventory OpenSSL versions across servers and packaged appliances.
  • Confirm whether systems run OpenSSL 3.0.4 specifically.
  • Check CPU capability for AVX512IFMA on x86_64 systems.
  • Identify services using 2048-bit RSA private keys.
  • Review TLS and application server configurations for RSA private-key use.
  • Track vendor advisory status for embedded OpenSSL dependencies.
