In the update to <code>2.34-60.7.el9_2.security.0.3</code>, we retained the mitigations while rebasing on upstream EL's package with upstream fixes for these vulnerabilities (and more).</p>
|

<p>In general, inclusion of additional security fixes will be "reverted" if and when those get included in upstream EL packages that we rebase our changes on.</p>
