<p>An update that solves one vulnerability, contains one feature and has one fix can now be installed.</p>
<h2>Description:</h2>
<p>This update for openCryptoki fixes the following issues</p>
<p>Security issue:</p>
<ul>
<li>CVE-2026-40253: Updated fix for malformed BER-encoded cryptographic objects
(bsc#1262283).</li>
</ul>
<p>Non security issue:</p>
<ul>
<li>Refactored .spec file to fully support transactional and immutable operating systems
(jsc#PED-14609):</li>
<li>Migrated user and group creation (pkcs11, pkcsslotd) from imperative %pre shell commands to
declarative systemd-sysusers configuration.</li>
<li>Replaced manual /var directory tracking and %ghost directives with
comprehensive systemd-tmpfiles configurations.</li>
<li>Implemented dynamic, architecture-specific tmpfiles.d generation to properly provision
hardware-specific token directories (e.g., ccatok, ep11tok, lite, and HSM_MK_CHANGE).</li>
<li>Fixed permissions for /run/opencryptoki within tmpfiles.d to ensure the
daemon can successfully drop privileges and bind its communication socket.</li>
<li>Moved 32-bit and 64-bit shared library symlink creation (such as PKCS11_API.so, stdll, and methods)
from %post scriptlets into the %install phase,
ensuring they are correctly packaged and tracked on the read-only /usr partition.</li>
<li>Removed legacy /etc/pkcs11 bash migration logic from %post,
replacing it with a declarative tmpfiles.d symlink rule.</li>
<li>Cleaned up scriptlets to only execute transaction-safe macros
(such as ldconfig and systemd service handlers).</li>
</ul>
