[1.4.3] - 2026-06-13

The best way to irritate him is to feed his grandmother to the Ravenous Bugblatter Beast of Traal.

Security

This release includes a fix for the following low-severity security issue:

• CVE-2026-41579 allowed a malicious image with a /dev symlink to have limited write access to the host filesystem in ways that our analysis indicates was too limited to be problematic in practice. This bug was very similar to those fixed in [CVE-2025-31133][], [CVE-2025-52565][], [CVE-2025-31133][] and was simply missed at the time when we hardened the rootfs preparation code. We have conducted a deeper audit and not found any other problematic cases.

Fixed

• Various integration test improvements. (#5222, #5237, #5226, #5229, #5239, #5249, #5269, #5287, #5295, #5304)

Changed

• When masking directories with maskPaths, runc will now reuse a single tmpfs instance (which is not writable) to reduce the number tmpfs superblocks that need to be reaped when containers die (in particular, Kubernetes applies masks to per-CPU sysfs directories which get expensive quickly). (#5275, #5281)

[1.3.6] - 2026-06-13

  This patchset required backports for #5190 and #5285, which were primarily code reorganisations that were already backported to runc 1.4 and 1.5.

Looks like github.com/opencontainers/runc is up-to-date now, so this is no longer needed.
