The negative length value wraps to a large unsigned size_t due to missing signed validation, bypasses an overflow-unsafe pointer arithmetic bounds check in wkb_parse_state_check(), and causes memcpy() in text_from_wkb_state() to operate with a corrupted unbounded length, resulting in a remote denial-of-service condition affecting all sessions on the PostgreSQL instance.","categories":["Unclassified"],"product":"MobilityDB","vendor":"MobilityDB","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102639","source_modified_at":"2026-10-02T12:19:12.738Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"MobilityDB","vendor":"MobilityDB","versions":[{"status":"affected","version":"1.1.0","versionType":"semver","lessThanOrEqual":"1.1.2"},{"status":"affected","version":"1.2.0","versionType":"semver","lessThan":"1.2.2"},{"status":"affected","version":"1.3.0","versionType":"semver","lessThan":"1.3.1"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102639","source_modified_at":"2026-10-02T12:19:12.738Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"MobilityDB","ecosystem":null},"version":"1.2.2","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102639","source_modified_at":"2026-10-02T12:19:12.738Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"MobilityDB","ecosystem":null},"version":"1.3.1","basis":"first unaffected version stated in the CVE record"}],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00324,"percentile":0.24287,"score_date":"2026-10-23"},"published_at":"2026-09-29T17:57:36.883Z","modified_at":"2026-10-02T12:19:12.738Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-102639","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-02T12:19:12.738Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-102639","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/MobilityDB/MobilityDB/security/advisories/GHSA-2c92-2w7c-pm3g","tags":["vendor-advisory","technical-description"]},{"source":"CVE List","url":"https://github.com/MobilityDB/MobilityDB/releases/tag/v1.3.1","tags":["patch"]},{"source":"CVE List","url":"https://github.com/MobilityDB/MobilityDB/releases/tag/v1.2.2","tags":["patch"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/mobilitydb-through-out-of-bounds-read-dos-via-wkb-deserialization","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":"2026-10-02T12:18:58.862526Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-02T12:19:12.738Z","content_hash":"e402c853335e7d808c703b9c1bea7b413d5b906146470c6efa0375acf930b6e6"}}
