{"cve":"CVE-2025-52565","nvd":{"published":"2025-11-06T20:15:49.240","modified":"2026-06-17T09:36:41.353","status":"Analyzed","description":"runc is a CLI tool for spawning and running containers according to the OCI specification. Versions 1.0.0-rc3 through 1.2.7, 1.3.0-rc.1 through 1.3.2, and 1.4.0-rc.1 through 1.4.0-rc.2, due to insufficient checks when bind-mounting `/dev/pts/$n` to `/dev/console` inside the container, an attacker can trick runc into bind-mounting paths which would normally be made read-only or be masked onto a path that the attacker can write to. This attack is very similar in concept and application to CVE-2025-31133, except that it attacks a similar vulnerability in a different target (namely, the bind-mount of `/dev/pts/$n` to `/dev/console` as configured for all containers that allocate a console). This happens after `pivot_root(2)`, so this cannot be used to write to host files directly -- however, as with CVE-2025-31133, this can load to denial of service of the host or a container breakout by providing the attacker with a writable copy of `/proc/sysrq-trigger` or `/proc/sys/kernel/core_pattern` (respectively). This issue is fixed in versions 1.2.8, 1.3.3 and 1.4.0-rc.3.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:H/VA:N/SC:H/SI:H/SA:H","score":8.4},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:H","score":7.5},"cwes":["CWE-61","CWE-363"],"references":["https://github.com/opencontainers/runc/commit/01de9d65dc72f67b256ef03f9bfb795a2bf143b4","https://github.com/opencontainers/runc/commit/398955bccb7f20565c224a3064d331c19e422398","https://github.com/opencontainers/runc/commit/531ef794e4ecd628006a865ad334a048ee2b4b2e","https://github.com/opencontainers/runc/commit/9be1dbf4ac67d9840a043ebd2df5c68f36705d1d","https://github.com/opencontainers/runc/commit/aee7d3fe355dd02939d44155e308ea0052e0d53a"],"products":["linuxfoundation:runc"],"source":"nvd","synced_at":"2026-10-19T22:14:53.307938015+00:00"},"epss":{"cve":"CVE-2025-52565","score":0.00811,"percentile":0.56958,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-qw9x-cqr3-wc7r","url":"https://osv.dev/vulnerability/GHSA-qw9x-cqr3-wc7r","summary":"runc container escape with malicious config due to /dev/console mount and related races","modified":"2026-09-10T03:50:58.358973597Z","packages":[{"ecosystem":"Go","name":"github.com/opencontainers/runc","purl":"pkg:golang/github.com/opencontainers/runc","ranges":[">=1.0.0-rc3 <1.2.8"],"fixed":["1.2.8"]},{"ecosystem":"Go","name":"github.com/opencontainers/runc","purl":"pkg:golang/github.com/opencontainers/runc","ranges":[">=1.3.0-rc.1 <1.3.3"],"fixed":["1.3.3"]},{"ecosystem":"Go","name":"github.com/opencontainers/runc","purl":"pkg:golang/github.com/opencontainers/runc","ranges":[">=1.4.0-rc.1 <1.4.0-rc.3"],"fixed":["1.4.0-rc.3"]}]},{"id":"GO-2025-4097","url":"https://osv.dev/vulnerability/GO-2025-4097","summary":"Container escape with malicious config due to /dev/console mount and related races in github.com/opencontainers/runc","modified":"2026-02-04T03:00:55.376695Z","packages":[{"ecosystem":"Go","name":"github.com/opencontainers/runc","purl":"pkg:golang/github.com/opencontainers/runc","ranges":[">=1.0.0-rc3 <1.2.8",">=1.3.0-rc.1 <1.3.3",">=1.4.0-rc.1 <1.4.0-rc.3"],"fixed":["1.2.8","1.3.3","1.4.0-rc.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
