Bumps

<h2>runc v1.2.8 -- "鳥籠の中に囚われた屈辱を"</h2>
<blockquote>
<p>[!NOTE]
Some vendors were given a pre-release version of this release.
This public release includes two extra patches to fix regressions
discovered very late during the embargo period and were thus not
included in the pre-release versions. Please update to this version.</p>
</blockquote>
<p>This release contains fixes for three high-severity security
vulnerabilities in runc (<a
href="https://github.com/opencontainers/runc/security/advisories/GHSA-9493-h29p-rfm2">CVE-2025-31133</a>,
<a
href="https://github.com/opencontainers/runc/security/advisories/GHSA-qw9x-cqr3-wc7r">CVE-2025-52565</a>,
and
<a
href="https://github.com/opencontainers/runc/security/advisories/GHSA-cgrx-mc8f-2prm">CVE-2025-52881</a>).
All three vulnerabilities ultimately allow (through
different methods) for full container breakouts by bypassing runc's
restrictions for writing to arbitrary <code>/proc</code> files.</p>
<h3>Security</h3>
<ul>
<li>
<p><a
href="https://github.com/opencontainers/runc/security/advisories/GHSA-9493-h29p-rfm2">CVE-2025-31133</a>
exploits an issue with how masked paths are implemented in
runc. When masking files, runc will bind-mount the container's
<code>/dev/null</code>
inode on top of the file. However, if an attacker can replace
<code>/dev/null</code>
with a symlink to some other procfs file, runc will instead bind-mount
the
symlink target read-write. This issue affected all known runc
versions.</p>
</li>
<li>
<p><a
href="https://github.com/opencontainers/runc/security/advisories/GHSA-qw9x-cqr3-wc7r">CVE-2025-52565</a>
is very similar in concept and application to
<a
href="https://github.com/opencontainers/runc/security/advisories/GHSA-9493-h29p-rfm2">CVE-2025-31133</a>,
except that it exploits a flaw in <code>/dev/console</code>
bind-mounts. When creating the <code>/dev/console</code> bind-mount (to
<code>/dev/pts/$n</code>),
if an attacker replaces <code>/dev/pts/$n</code> with a symlink then
runc will
bind-mount the symlink target over <code>/dev/console</code>. This issue
affected all
versions of runc >= 1.0.0-rc3.</p>
</li>
<li>
<p><a
href="https://github.com/opencontainers/runc/security/advisories/GHSA-cgrx-mc8f-2prm">CVE-2025-52881</a>
is a more sophisticated variant of <a
href="https://github.com/opencontainers/runc/security/advisories/GHSA-fh74-hm69-rqjw">CVE-2019-19921</a>,
which was a flaw that allowed an attacker to trick runc into writing the
LSM
process labels for a container process into a dummy tmpfs file and thus
not
apply the correct LSM labels to the container process. The mitigation we
applied for <a
href="https://github.com/opencontainers/runc/security/advisories/GHSA-fh74-hm69-rqjw">CVE-2019-19921</a>
was fairly limited and effectively only caused
runc to verify that when we write LSM labels that those labels are
actual
procfs files. This issue affects all known runc versions.</p>

<h2>[1.2.7] - 2025-09-05</h2>

<p>さんをつけろよデコ助野郎！</p>
</blockquote>
<h3>Fixed</h3>
<ul>
<li>Removed preemptive "full access to cgroups" warning when
calling <code>runc pause</code> or <code>runc unpause</code> as an
unprivileged user without
<code>--systemd-cgroups</code>. Now the warning is only emitted if an
actual permission
error was encountered. (<a
href="https://redirect.github.com/opencontainers/runc/issues/4709">#4709</a>,
<a
href="https://redirect.github.com/opencontainers/runc/issues/4720">#4720</a>)</li>
<li>Add time namespace to container config after checkpoint/restore.
CRIU since
version 3.14 uses a time namespace for checkpoint/restore, however it
was
not joining the time namespace in runc. (<a
href="https://redirect.github.com/opencontainers/runc/issues/4696">#4696</a>,
<a
href="https://redirect.github.com/opencontainers/runc/issues/4714">#4714</a>)</li>
<li>Container processes will no longer inherit the CPU affinity of runc
by
default. Instead, the default CPU affinity of container processes will
be
the largest set of CPUs permitted by the container's cpuset cgroup and
any
other system restrictions (such as isolated CPUs). (<a
href="https://redirect.github.com/opencontainers/runc/issues/4041">#4041</a>,
