<p>An update that solves one vulnerability can now be installed.</p>
<h2>Description:</h2>
<p>This update for runc fixes the following issues:</p>
<p>Update to 1.3.6.</p>
<ul>
<li>CVE-2026-41579: malicious image with a <code>/dev</code> symlink can trigger limited host filesystem integrity violations
(bsc#1268275).</li>
</ul>
<p>Other updates and bugfixes:</p>
<ul>
<li>Version 1.3.6:</li>
<li>When masking directories with <code>maskPaths</code>, runc will now re- use a single <code>tmpfs</code> instance (which is not writeable)
to reduce the number <code>tmpfs</code> superblocks that need to be reaped when containers die (in particular, Kubernetes
applies masks to per-CPU sysfs directories which get expensive quickly).</li>
<li>Version 1.3.5:</li>
<li>Recursive atime-related mount flags (rrelatime et al.) are now applied properly.</li>
<li>PR #4757 caused a regression that resulted in spurious cannot start a container that has stopped errors when
running runc create and has thus been reverted.</li>
<li>Updated builds to Go 1.25, libseccomp v2.6.0.</li>
<li>Minor signing keyring updates.</li>
</ul>
