{"cve":"CVE-2026-24834","nvd":{"published":"2026-02-19T17:24:49.823","modified":"2026-07-15T02:18:51.330","status":"Modified","description":"Kata Containers is an open source project focusing on a standard implementation of lightweight Virtual Machines (VMs) that perform like containers. In versions prior to 3.27.0, an issue in Kata with Cloud Hypervisor allows a user of the container to modify the file system used by the Guest micro VM ultimately achieving arbitrary code execution as root in said VM. The current understanding is this doesn’t impact the security of the Host or of other containers / VMs running on that Host (note that arm64 QEMU lacks NVDIMM read-only support: It is believed that until the upstream QEMU gains this capability, a guest write could reach the image file). Version 3.27.0 patches the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":8.8},"cwes":["CWE-732","CWE-281"],"references":["https://github.com/kata-containers/kata-containers/commit/6a672503973bf7c687053e459bfff8a9652e16bf","https://github.com/kata-containers/kata-containers/releases/tag/3.27.0","https://github.com/kata-containers/kata-containers/security/advisories/GHSA-wwj6-vghv-5p64","https://access.redhat.com/security/cve/CVE-2026-24834","https://bugzilla.redhat.com/show_bug.cgi?id=2441025"],"products":["katacontainers:kata_containers"],"source":"nvd","synced_at":"2026-10-19T22:23:35.260773158+00:00"},"epss":{"cve":"CVE-2026-24834","score":0.00244,"percentile":0.15696,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-wwj6-vghv-5p64","url":"https://osv.dev/vulnerability/GHSA-wwj6-vghv-5p64","summary":"Kata Container to Guest micro VM privilege escalation","modified":"2026-09-10T03:50:36.137590460Z","packages":[{"ecosystem":"Go","name":"github.com/kata-containers/kata-containers/src/runtime","purl":"pkg:golang/github.com/kata-containers/kata-containers/src/runtime","ranges":["<0.0.0-20260219090056-6a672503973b"],"fixed":["0.0.0-20260219090056-6a672503973b"]}]},{"id":"GO-2026-4517","url":"https://osv.dev/vulnerability/GO-2026-4517","summary":"Kata Container to Guest micro VM privilege escalation in github.com/kata-containers/kata-containers/src/runtime","modified":"2026-02-23T19:41:13.971542Z","packages":[{"ecosystem":"Go","name":"github.com/kata-containers/kata-containers/src/runtime","purl":"pkg:golang/github.com/kata-containers/kata-containers/src/runtime","ranges":["<0.0.0-20260219090056-6a672503973b"],"fixed":["0.0.0-20260219090056-6a672503973b"]}]}],"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).
