Vulnerability from cvelistv5 – Published: 2026-09-10 08:24 – Updated: 2026-09-15 16:23

Title

Crun: crun: rootful krun with passt executes container payload as host root

Summary

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

Severity

7.8 (High)

CVE-2026-88264 (GCVE-0-2026-88264)

Vulnerability from cvelistv5 – Published: 2026-09-10 08:40 – Updated: 2026-09-25 22:28

Title

Crun: crun: /dev/console symlink follow allows root-owned file creation outside the rootfs

Summary

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.

Severity

5.6 (Medium)

CVE-2026-88265 (GCVE-0-2026-88265)

Vulnerability from cvelistv5 – Published: 2026-09-10 08:57 – Updated: 2026-10-02 13:59

Title

Crun: crun: /dev/null symlink follow during stdio reopen allows host bind-mount write and chown

Summary

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.

Severity

5.6 (Medium)
