Summary

This update for runc fixes the following issues: Update to runc v1.0.3. * CVE-2021-43784: Fixed a potential vulnerability related to the internal usage of netlink, which is believed to not be exploitable with any released versions of runc (bsc#1193436) * Fixed inability to start a container with read-write bind mount of a read-only fuse host mount. * Fixed inability to start when read-only /dev in set in spec. * Fixed not removing sub-cgroups upon container delete, when rootless cgroup v2 is used with older systemd. * Fixed returning error from GetStats when hugetlb is unsupported (which causes excessive logging for kubernetes).
