runc v1.3.3 -- "奴らに支配されていた恐怖を"
[!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.
This release contains fixes for three high-severity security vulnerabilities in runc (CVE-2025-31133, CVE-2025-52565, and CVE-2025-52881). All three vulnerabilities ultimately allow (through different methods) for full container breakouts by bypassing runc's restrictions for writing to arbitrary
/procfiles.Security
CVE-2025-31133 exploits an issue with how masked paths are implemented in runc. When masking files, runc will bind-mount the container's
/dev/nullinode on top of the file. However, if an attacker can replace/dev/nullwith a symlink to some other procfs file, runc will instead bind-mount the symlink target read-write. This issue affected all known runc versions.CVE-2025-52565 is very similar in concept and application to CVE-2025-31133, except that it exploits a flaw in
/dev/consolebind-mounts. When creating the/dev/consolebind-mount (to/dev/pts/$n), if an attacker replaces/dev/pts/$nwith a symlink then runc will bind-mount the symlink target over/dev/console. This issue affected all versions of runc >= 1.0.0-rc3.CVE-2025-52881 is a more sophisticated variant of CVE-2019-19921, 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 CVE-2019-19921 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.
