Alpine: multiple crun packages: security update to 1.30.1-r0
high Tenable Self-Hosted Container Security Plugin ID 448442
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- A flaw was found in crun. When crun is built with libkrun and a container is started rootful with passt
networking (krun.use_passt), crun can execute attacker-controlled payload from the container image with
host root privileges. The issue is a regression in crun 1.29. It affects crun >= 1.29 (CVE-2026-84042)
- A flaw was found in crun. When the container configuration does not give /dev a dedicated mount, terminal
setup can redirect /dev/console onto an attacker-controlled path, including via the read-only-rootfs bind-
mount fallback. Affected versions are crun 1.29.1 and earlier. Default configurations that mount a fresh
/dev are not exposed. No fixed release is available yet. (CVE-2026-88264)
- A flaw was found in crun. After pivot_root, reopening /dev/null for stdio can follow a symlink and attach
a host file to container stdio, then change that file's ownership. Affected versions are crun 1.29.1 and
earlier. Default configurations that mount a fresh /dev are not exposed. No fixed release is available
yet. (CVE-2026-88265)
Solution
Update the crun library and its related packages to version 1.30.1-r0 or later.See Also
