It contains the security rules under which the module must operate and describes how this module meets the requirements as specified in FIPS PUB 140-3 (Federal Information Processing Standards Publication 140-3) for an overall Security Level 1 module. This Non-Proprietary Security Policy may be reproduced and distributed, but only whole and intact and including this notice. Other documentation is proprietary to their authors. 1.1.1 How this Security Policy was prepared In preparing the Security Policy document, the laboratory formatted the vendor-supplied documentation for consolidation without altering the technical statements therein contained. The further refining of the Security Policy document was conducted iteratively throughout the conformance testing, wherein the Security Policy was submitted to the vendor, who would then edit, modify, and add technical contents. The vendor would also supply additional documentation, which the laboratory formatted into the existing Security Policy, and resubmitted to the vendor for their final editing. 1.2 Security Levels Section Title Security Level 1 General 1 2 Cryptographic module specification 1 3 Cryptographic module interfaces 1 4 Roles, services, and authentication 1 5 Software/Firmware security 1 6 Operational environment 1 7 Physical security N/A 8 Non-invasive security N/A 9 Sensitive security parameter management 1 10 Self-tests 1 11 Life-cycle assurance 1 12 Mitigation of other attacks N/A Overall Level 1 Table 1: Security Levels © 2026 Red Hat, LLC/ atsec information security corporation.

Page 7 of 87 2 Cryptographic Module Specification 2.1 Description Purpose and Use: The Red Hat Enterprise Linux 8 Kernel Cryptographic API (hereafter referred to as “the module”) provides a C language application program interface (API) for use by other (kernel space and user space) processes that require cryptographic functionality. The module operates on a general-purpose computer as part of the Linux kernel. Its cryptographic functionality can be accessed using the Linux Kernel Crypto API. Module Type: Software Module Embodiment: Multi-Chip Standalone Cryptographic Boundary: The cryptographic boundary of the module is defined as the kernel binary and the kernel crypto object files, the libkcapi library, and the sha512hmac binary, which is used to verify the integrity of the software components. In addition, the cryptographic boundary contains the .hmac files which store the expected integrity values for each of the software components. Tested Operational Environment’s Physical Perimeter (TOEPP): The TOEPP of the module is defined as the general-purpose computer on which the module is installed. The PAA/PAI provided by the processor are located within the module’s physical perimeter and outside of the module’s cryptographic boundary.

Page 10 of 87 2.3 Excluded Components There are no components within the cryptographic boundary excluded from the FIPS 140-3 requirements. 2.4 Modes of Operation Modes List and Description: Mode Name Description Type Status Indicator Approved mode Automatically entered whenever an approved service is requested Approved Mapped to approved service indicator in Section 4.3 for all approved algorithms except GCM: respective approved service function returns indicator 0. For GCM: crypto_aead_get_flags(tfm) has the CRYPTO_TFM_FIPS_COMPLIANCE flag set Non- approved mode Automatically entered whenever a non-approved service is requested Non- Approved No service indicator required for non-approved services per IG 2.4.C Table 5: Modes List and Description Once the module is installed and initilized as per Section 11.1, after passing all pre-operational self-tests and cryptographic algorithm self-tests executed on start-up, the module automatically transitions to the approved mode. On startup, no operator intervention is required to reach this point. Mode Change Instructions and Status: The module automatically switches between the approved and non-approved modes depending on the services requested by the operator. The status indicator of the mode of operation is equivalent to the indicator of the service that was requested. 2.5 Algorithms Approved Algorithms: Algorithm CAVP Cert Properties Reference AES-CBC A7185, A7189, A7197, A7202, A7205, A7402 Direction - Decrypt, Encrypt Key Length - 128, 192, 256 SP 800-38A AES-CBC-CS3 A7193, A7200, A7209 Direction - decrypt, encrypt Key Length - 128, 192, 256 SP 800-38A © 2026 Red Hat, LLC/ atsec information security corporation.

For IPsec, the module offers the AES GCM implementation and uses the context of Scenario 1 of FIPS 140-3 IG C.H. The mechanism for IV generation is compliant with RFC 4106. IVs generated using this mechanism may only be used in the context of AES GCM encryption within the IPsec protocol. The module does not implement IPsec. The module’s implementation of AES GCM is used together with an application that runs outside the module’s cryptographic boundary. This application must use RFC 7296 compliant IKEv2 to establish the shared secret SKEYSEED from which the AES GCM encryption keys are derived. The design of the IPsec protocol implicitly ensures that the counter (the nonce_explicit part of the IV) does not exhaust the maximum number of possible values for a given session key. In the event the module’s power is lost and restored, the consuming application must ensure that a new key for use with the AES GCM key encryption or decryption under this scenario shall be established. The module also provides a non-approved AES GCM encryption service which accepts arbitrary external IVs from the operator. This service can be requested by invoking the crypto_aead_encrypt API function with an AES GCM handle. When this is the case, the API will not set an approved service indicator, as described in section 4.3. 2.7.2 AES XTS The length of a single data unit encrypted or decrypted with AES XTS shall not exceed 220 AES blocks, that is 16MB, of data per XTS instance. An XTS instance is defined in Section 4 of SP 800-38E. The XTS mode shall only be used for the cryptographic protection of data on storage devices. It shall not be used for other purposes, such as the encryption of data in transit. To meet the requirement stated in IG C.I, the module implements a check to ensure that the two AES keys used in AES XTS mode are not identical. As the module does not implement symmetric key generation, this check is performed when the keys are input by the operator. Key_1 and Key_2 shall be generated and/or established independently according to the rules for component symmetric keys from NIST SP 800-133r2, Section 6.3. © 2026 Red Hat, LLC/ atsec information security corporation.

Page 19 of 87 2.7.3 RSA For RSA signature verification, the module supports modulus size 3072 bits. The supported modulus size has been CAVP tested. 2.7.4 SHA-3 The module provides SHA-3 hash functions compliant with IG C.C. Every implementation of each SHA-3 function was tested and validated on all the module’s operating environments. SHAKE functions are not implemented. SHA-3 hash functions are also used as part of a higher-level algorithm for HMAC. 2.7.5 SHA-1 Digital signature generation using SHA-1 is non-approved and not allowed in approved services. 2.8 RBG and Entropy Cert Number Vendor Name E174 Red Hat, LLC Table 9: Entropy Certificates Name Type Operational Environment Sample Size Entropy per Sample Conditioning Component RHEL 8 Kernel CPU Time Jitter RNG Entropy Source Non- Physical Red Hat Enterprise Linux 8 on Dell PowerEdge R440; Red Hat Enterprise Linux 8 on IBM z15 8561-T01; Red Hat Enterprise Linux 8 on IBM 9009-42A; Red Hat Enterprise Linux 8 on IBM 9080-HEX 64 bits 57 bits Linear-Feedback Shift Register (LFSR) Table 10: Entropy Sources The module implements three different Deterministic Random Bit Generator (DRBG) implementations based on SP 800-90Ar1: Counter DRBG, Hash DRBG, and HMAC DRBG. Each of these DRBG implementations can be instantiated by the operator of the module, using the parameters listed specified in the Security Function Implementations table. When instantiated, these DRBGs can be used to generate random numbers for external usage. © 2026 Red Hat, LLC/ atsec information security corporation. This document can be reproduced and distributed only whole and intact, including this copyright notice. Page 20 of 87 The module complies with the Public Use Document for ESV certificate E174 by reading entropy data from the jent_kcapi_random() function, which corresponds to the GetEntropy() conceptual interface. This function outputs 256 bits of full entropy. The operational environment on the ESV certificate is identical to the operating system described in this document, and the entropy source is implemented inside the cryptographic boundary. Thus, the module is compliant with scenario 1 of IG 9.3.A. There are no maintenance requirements for the entropy source. 2.9 Key Generation The module does not provide key generation. 2.10 Key Establishment The module does not provide key establishment. 2.11 Industry Protocols AES GCM with internal IV generation in the approved mode is compliant with RFC 4106 and shall only be used in conjunction with the IPsec protocol. No parts of this protocol, other than the AES GCM implementation, have been tested by the CAVP and CMVP. © 2026 Red Hat, LLC/ atsec information security corporation.

Page 28 of 87 5 Software/Firmware Security 5.1 Integrity Techniques The static kernel binary is integrity tested using an HMAC-SHA2-512 calculation performed by the sha512hmac utility (which utilizes the module’s HMAC and SHA-512 implementations). The sha512hmac utility first executes the HMAC-SHA2-512 self-test. After this self-test is successful, the sha512hmac utility is used to perform an HMAC calculation of the libkcapi library, the kernel binary, and of its own binary to verify their integrity. After the integrity of these components has been verified, the self-test for the RSA signature verification implementation is run. Upon successful run of this self-test, the RSA signature verification implementation of the kernel (with PKCS#1 v1.5 padding, SHA-256, and a 3072-bit key) is used to verify the integrity of the crypto object files listed in section 2.2 and loaded at start-up. 5.2 Initiate on Demand Integrity tests are performed as part of the pre-operational self-tests, which are executed when the module is initialized. The integrity tests can be invoked on demand by unloading and subsequently re-initializing the module, which will perform (among others) the software integrity tests. © 2026 Red Hat, LLC/ atsec information security corporation.

Page 29 of 87 6 Operational Environment 6.1 Operational Environment Type and Requirements Type of Operational Environment: Modifiable How Requirements are Satisfied: The operating system provides process isolation and memory protection mechanisms that ensure appropriate separation for memory access among the processes on the system. Each process has control over its own data and uncontrolled access to the data of other processes is prevented. 6.2 Configuration Settings and Restrictions The module shall be installed as stated in Section 11.1. Instrumentation tools like the ptrace system call, gdb and strace, as well as other tracing mechanisms offered by the Linux environment such as ftrace or systemtap, shall not be used in the operational environments. The use of any of these tools implies that the cryptographic module is running in a non-validated operational environment. 6.3 Additional Information The Red Hat Enterprise Linux operating system is used as the basis of other products which include but are not limited to: • Red Hat Enterprise Linux CoreOS • Red Hat Ansible Automation Platform • Red Hat OpenStack Platform • Red Hat OpenShift • Red Hat Gluster Storage • Red Hat Satellite Compliance is maintained for these products whenever the binary is found unchanged. © 2026 Red Hat, LLC/ atsec information security corporation.

Integrity test for kernel crypto object files Table 20: Pre-Operational Self-Tests The pre-operational software integrity tests are performed automatically when the module is powered on, before the module transitions into the operational state. The algorithms used for the integrity test (i.e., HMAC- SHA2-512 and RSA SigVer with 3072-bit key) run their CASTs before the integrity test is performed. While the module is executing the self-tests, services are not available, and data output (via the data output interface) is inhibited until the pre-operational software integrity self-tests are successfully completed. The module transitions to the operational state only after the pre-operational self-tests are passed successfully. 10.2 Conditional Self-Tests Algorithm or Test Test Properties Test Method Test Type Indicator Details Conditions SHA-1 (A7194) 0-8184 bit messages KAT CAST Module becomes operational and services are available for use.

Page 83 of 87 11 Life-Cycle Assurance 11.1 Installation, Initialization, and Startup Procedures The module is distributed as a part of the Red Hat Enterprise Linux 8 (RHEL 8) package in the form of the kernel-4.18.0-553.123.1.el8_10, libkcapi-1.4.0-2.el8, and libkcapi-hmaccalc-1.4.0-2.el8 RPM packages. The module can achieve FIPS validated configuration by: • For installation add the fips=1 option to the kernel command line during the system installation. During the software selection stage, do not install any third-party software. More information can be found at the vendor documentation. • Switching the system into the approved mode the installation. Execute the fips-mode-setup --enable command. Restart the system. More information can be found at the vendor documentation. In both cases, the Crypto Officer must verify the RHEL 8 system operates in the approved mode by executing the “fips-mode-setup --check” command, which should output “FIPS mode is enabled.” 11.2 Administrator Guidance After installation of the kernel-4.18.0-553.123.1.el8_10, libkcapi-1.4.0-2.el8, and libkcapi-hmaccalc-1.4.0-2.el8 RPM packages, the Crypto Officer must execute the “cat /proc/sys/crypto/fips_name” command. The Crypto Officer must ensure that the proper name is listed in the output as follows: Red Hat Enterprise Linux 8 - Kernel Cryptographic API Then, the Crypto Officer must execute the “cat /proc/sys/crypto/fips_version” and “rpm -q libkcapi” commands. These commands must output the following (one line per output): 4.18.0-553.123.1.el8_10.x86_64 libkcapi-1.4.0-2.el8.x86_64 11.3 Non-Administrator Guidance There is no non-administrator guidance. 11.6 End of Life As the module does not persistently store SSPs, secure sanitization of the module consists of unloading the module. This will zeroize all SSPs in volatile memory. Then, if desired, the kernel-4.18.0-553.123.1.el8_10, libkcapi-1.4.0-2.el8, and libkcapi-hmaccalc-1.4.0-2.el8 RPM packages can be uninstalled from the RHEL 8 system. © 2026 Red Hat, LLC/ atsec information security corporation.
