In versions 1.2.7 and below, 1.3.0-rc.1 through 1.3.1, 1.4.0-rc.1 and 1.4.0-rc.2 files, runc would not perform sufficient verification that the source of the bind-mount (i.e., the container&#8217;s \/dev\/null) was actually a real \/dev\/null inode when using the container&#8217;s \/dev\/null to mask. This exposes two methods of attack:  an arbitrary mount gadget, leading to host information disclosure, host denial of service, container escape, or a bypassing of maskedPaths. This issue is fixed in versions 1.2.8, 1.3.3 and 1.4.0-rc.3.<\/p>\n<p>Severity: 0.0 | NA<\/p>\n<p>Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID : CVE-2025-31133 Published : Nov. 6, 2025, 6:47 p.m. | 42\u00a0minutes ago Description : runc is a CLI tool for spawning and running containers according to the OCI specification.
