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.
libcontainer API
  • The cmsg helpers from github.com/opencontainers/runc/libcontainer/utils
    have been moved to an internal package. We have included wrapper functions
    but they will be removed in runc 1.6. (#​5227, #​5231)
  • Added //go:fix inline to ease migration for libcontainer/devices symbols
    that are deprecated and scheduled for removal in runc 1.6. (#​5223, #​5225)
Fixed
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, #​5280)
