<p>An update that solves one vulnerability and has two fixes can now be installed.</p>
<h2>Description:</h2>
<p>This update for systemd fixes the following issues:</p>
<ul>
<li>Remove the script used to help migrating the language and locale settings
located in /etc/sysconfig/language on old systems to the systemd default
locations (bsc#1247074)</li>
</ul>
<p>The script was introduced more than 7 years ago and all systems running TW
should have been migrated since then. Moreover the installer supports the
systemd default locations since approximately SLE15. </p>
<ul>
<li>
<p>triggers.systemd: skip update of hwdb, journal-catalog if executed during an
offline update.</p>
</li>
<li>
<p>logs-show: get timestamp and boot ID only when necessary (bsc#1242827)</p>
</li>
<li>sd-journal: drop to use Hashmap to manage journal files per boot ID</li>
<li>tree-wide: set SD_JOURNAL_ASSUME_IMMUTABLE where appropriate</li>
<li>sd-journal: introduce SD_JOURNAL_ASSUME_IMMUTABLE flag</li>
<li>sd-journal: make journal_file_read_tail_timestamp() notify to the caller that some new journal entries added</li>
<li>sd-journal: cache last entry offset and journal file state</li>
<li>
<p>sd-journal: fix typo in function name</p>
</li>
<li>
<p>coredump: use %d in kernel core pattern (bsc#1243935 CVE-2025-4598)</p>
</li>
</ul>
