  * SUSE Linux Enterprise Server for SAP Applications 16.0

An update that solves two vulnerabilities and contains two features can now be
installed.

## Description:

This update for openCryptoki fixes the following issues:

Upgrade openCryptoki to 3.26 (jsc#PED-14609)

Security fixes:

  * CVE-2026-22791: supplying malformed compressed EC public key can lead to
    heap corruption or denial-of-service (bsc#1256673).
  * CVE-2026-23893: Privilege Escalation or Data Exposure via Symlink Following
    (bsc#1257116).

Other fixes:

  * Soft: Add support for RSA keys up to 16K bits.
  * CCA: Add support for RSA keys up to 8K bits (requires CCA v8.4 or v7.6 or
    later).
  * p11sak: Add support for generating RSA keys up to 16K bits.
  * Soft/ICA: Add support for SHA512/224 and SHA512/256 key derivation mechanism
    (CKM_SHA512_224_KEY_DERIVATION and CKM_SHA512_256_KEY_DERIVATION).
  * Soft/ICA/CCA/EP11: Add support for SHA-HMAC key types CKK_SHAxxx_HMAC and
    key gen mechanisms CKM_SHAxxx_KEY_GEN.
  * p11sak: Add support for SHA-HMAC key types and key generation.
  * p11sak: Add support for key wrap and unwrap commands to export and import
    private and secret keys by means of key wrapping/unwrapping with various key
    wrapping mechanism.
  * p11kmip: Add support for using an HSM-protected TLS client key via a PKCS#11
    provider.
  * p11sak: Add support for exporting non-sensitive private keys to password
    protected PEM files.

    C_XxxInit() call as an alternative to C_SessionCancel() (PKCS#11 v3.0).
  * EP11: Add support for pairing friendly BLS12-381 EC curve for sign/verify
    using CKM_IBM_ECDSA_OTHER and signature/public key aggregation using
    CKM_IBM_EC_AGGREGATE.
  * p11sak: Add support for generating BLS12-381 EC keys.
  * EP11: Add support for IBM-specific ML-DSA and ML-KEM key types and
    mechanisms (requires an EP11 host library v4.2 or later, and a CEX8P crypto
    card with firmware v9.6 or later on IBM z17, and v8.39 or later on IBM z16).
  * CCA: Add support for IBM-specific ML-DSA and ML-KEM key types and mechanisms
    (requires CCA v8.4 or later).
  * Soft: Add support for IBM-specific ML-DSA and ML-KEM key types and
