Name of the Vulnerable Software and Affected Versions
Docker Sandboxes (affected versions not specified)
Description
Docker Sandboxes (sbx) incorrectly applies the read-only intent of a runtime host mount, limiting it only to the in-guest container bind. The underlying virtio-fs host-edge grant is added to the sandbox's policy-share allowlist without an access mode. Consequently, the directory remains writable at its shared-export path, allowing unprivileged code within the sandbox to identify that path and write to a host directory intended to be read-only.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
