What is SUSE-SU-2026:4441-1?
SUSE-SU-2026:4441-1 is a vulnerability in kubevirt-1.6, published on 5 Oct 2026.
Official description
This update for kubevirt-1.6 fixes the following issues:
- Package the persistent-reservation helper's entrypoint script (bsc#1276520): virt-operator runs the pr-helper container with the command /entrypoint.sh, which symlinks the multipath socket into place and then execs qemu-pr-helper. Only multipath.conf was installed, so the container could not start and persistent reservation was unavailable. The script is upstream in cmd/pr-helper/entrypoint.sh.
