    * JDK: Improve JMX connections (CVE-2026-21925)

    Bug Fix(es):

      * When using a P11SecretKey for both signing and encryption in FIPS mode, the FIPS PKCS11 provider would
    fail with a CKR_ATTRIBUTE_VALUE_INVALID error. This was due to the default configuration not applying the
    CKA_ENCRYPT=true attribute to the key. The configuration in this release is updated to include this
    attribute. (AlmaLinux-142865, AlmaLinux-142866, AlmaLinux-142867, AlmaLinux-142868, AlmaLinux-142869,
    AlmaLinux-142870, AlmaLinux-142871, AlmaLinux-142872, AlmaLinux-142873, AlmaLinux-142874)

Tenable has extracted the preceding description block directly from the AlmaLinux security advisory.
