{"cve":"CVE-2025-0624","nvd":{"published":"2025-02-19T19:15:15.120","modified":"2026-10-13T03:16:39.887","status":"Deferred","description":"A flaw was found in grub2. During the network boot process, when trying to search for the configuration file, grub copies data from a user controlled environment variable into an internal buffer using the grub_strcpy() function. During this step, it fails to consider the environment variable length when allocating the internal buffer, resulting in an out-of-bounds write. If correctly exploited, this issue may result in remote code execution through the same network segment grub is searching for the boot information, which can be used to by-pass secure boot protections.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H","score":7.6},"cwes":["CWE-787"],"references":["https://access.redhat.com/errata/RHSA-2025:2521","https://access.redhat.com/errata/RHSA-2025:2653","https://access.redhat.com/errata/RHSA-2025:2655","https://access.redhat.com/errata/RHSA-2025:2675","https://access.redhat.com/errata/RHSA-2025:2784"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:59:18.731010617+00:00"},"epss":{"cve":"CVE-2025-0624","score":0.01405,"percentile":0.72388,"date":"2026-10-25"},"kev":null,"osv":[],"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).
