As a result, an attacker can remove the disk, use another server to modify the files in the config partition, and then re-insert the disk.\n\n### Patches\n\nFixed in EVE version 9.4.3-lts\n\n### Workarounds\n\nNone (apart from preventing physical access to the device)\n\n### Resources\n\nhttps://help.zededa.com/hc/en-us/articles/43295940828827-TPM-PCR-Index-Security-Implications\nhttps://github.com/lf-edge/eve/commit/d9383a7ee4e1c39f5c8c6d4a63cb2ebd00695e8a","affected":[{"package":{"name":"github.com/lf-edge/eve","ecosystem":"Go","purl":"pkg:golang/github.com/lf-edge/eve"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.0.0-20230519072751-977f42b07fa9"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/02/GHSA-wc42-fcjp-v8vq/GHSA-wc42-fcjp-v8vq.json"}}],"references":[{"type":"WEB","url":"https://github.com/lf-edge/eve/security/advisories/GHSA-wc42-fcjp-v8vq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-43634"},{"type":"WEB","url":"https://asrg.io/security-advisories/config-partition-not-protected-by-measured-boot"},{"type":"WEB","url":"https://asrg.io/security-advisories/cve-2023-43634"},{"type":"PACKAGE","url":"https://github.com/lf-edge/eve"}],"database_specific":{"cwe_ids":["CWE-522","CWE-922"],"github_reviewed":true,"github_reviewed_at":"2026-02-04T21:38:32Z","nvd_published_at":null,"severity":"MODERATE"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:P/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:N"}]}
