Attackers can supply a malicious BitLocker volume image with a datum_size smaller than the 36-byte AES-CCM header, causing hexdump() to over-read and crash dislocker.","categories":["Unclassified"],"product":"dislocker","vendor":"Aorimn","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-107635","source_modified_at":"2026-10-16T11:38:58.060Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"dislocker","vendor":"Aorimn","versions":[{"version":"0","lessThanOrEqual":"0.7.3","status":"affected","versionType":"custom"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.9,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00129,"percentile":0.02263,"score_date":"2026-10-23"},"published_at":"2026-10-08T14:10:33.744Z","modified_at":"2026-10-16T11:38:58.060Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-107635","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T11:38:58.060Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-107635","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/Aorimn/dislocker/commit/0706462db88efe8df88150e4c3e4332b808f4581","tags":["patch"]},{"source":"CVE List","url":"https://github.com/Aorimn/dislocker/blob/v0.7.3/src/metadata/vmk.c#L146-L180","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/Aorimn/dislocker/blob/v0.7.3/src/metadata/fvek.c#L90-L105","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/Aorimn/dislocker","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/dislocker-through-0.7.3-out-of-bounds-heap-read-via-vmk-fvek-datum-size-underflow","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-08T16:05:14.829892Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-16T11:38:58.060Z","content_hash":"3713c37cff7626d0674ccb1423fb40713dc11b3a6b7ac273afabd724371342ce"}}
