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.","publishedAt":"2026-09-03T01:04:45.189Z","updatedAt":"2026-09-03T14:30:54.637Z","severity":{"score":5.2,"label":"Medium","version":"4.0","vector":"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","source":"VulnCheck"},"assigner":"VulnCheck","products":["jtsylve LiME"],"affected":[{"vendor":"jtsylve","product":"LiME","packageURL":"pkg:github/jtsylve/LiME","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.12.0","versionType":"semver"}]}],"references":["https://gist.github.com/thesmartshadow/5355949144749b431da41490b63598f5","https://github.com/jtsylve/LiME/blob/v1.12.0/src/disk.c#L63","https://github.com/jtsylve/LiME","https://www.vulncheck.com/advisories/lime-through-1.12.0-arbitrary-file-overwrite-via-symlink-following"],"weaknesses":["CWE-59"],"ingestedAt":"2026-10-29T20:13:15.269Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/85xxx/CVE-2026-85092.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-85092","state":"PUBLISHED","datePublished":"2026-09-03T01:04:45.189Z","dateUpdated":"2026-09-03T14:30:54.637Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-09-02T23:53:09.796Z"},"containers":{"cna":{"title":"LiME through 1.12.0 Arbitrary File Overwrite via Symlink Following","descriptions":[{"lang":"en","value":"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.
