{"id":"CVE-2026-85092","summary":"LiME through 1.12.0 Arbitrary File Overwrite via Symlink Following","details":"LiME through 1.12.0 fails to validate the disk acquisition output path and does not use O_NOFOLLOW when opening the operator-supplied path parameter, allowing unprivileged local users to overwrite arbitrary root-owned files. An attacker who controls the output directory can create a symbolic link with the expected filename pointing to any root-owned file, and when the acquisition runs in kernel context, LiME follows the link and truncates the target file with the memory acquisition stream.","modified":"2026-09-03T11:46:00.321890559Z","published":"2026-09-03T01:04:45.189Z","database_specific":{"cwe_ids":["CWE-59"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/85xxx/CVE-2026-85092.json","cna_assigner":"VulnCheck"},"references":[{"type":"EVIDENCE","url":"https://gist.github.com/thesmartshadow/5355949144749b431da41490b63598f5"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/85xxx/CVE-2026-85092.json"},{"type":"PACKAGE","url":"https://github.com/jtsylve/LiME"},{"type":"ARTICLE","url":"https://github.com/jtsylve/LiME/blob/v1.12.0/src/disk.c#L63"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-85092"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/lime-through-1.12.0-arbitrary-file-overwrite-via-symlink-following"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/jtsylve/lime","events":[{"introduced":"0"},{"last_affected":"a1205ccf98216095623280a2a026e0eee60916af"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"1.12.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v1.12.0","v1.11.0","v1.10.1","v1.10.0","v1.9.1","v1.9","v1.8.1","v1.8","v1.7.8","v1.7.7","v1.7.6","v1.7.5","1.7.5","v1.7.4","v1.7.3","v1.7.2","v1.7.1","v1.7","v1.5","v1.4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-85092.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:P/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
