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.","epss":{"date":"2026-11-08","percentile":0.25676,"score":0.00324},"exploits":[],"kev":null,"metrics":[{"score":7.1,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":6.5,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1794146443896,"publishedAt":1790704656883,"references":[{"source":"CNA: VulnCheck","tags":["vendor-advisory","technical-description"],"url":"https://github.com/MobilityDB/MobilityDB/security/advisories/GHSA-2c92-2w7c-pm3g"},{"source":"CNA: VulnCheck","tags":["patch","release-notes"],"url":"https://github.com/MobilityDB/MobilityDB/releases/tag/v1.3.1"},{"source":"CNA: VulnCheck","tags":["patch","release-notes"],"url":"https://github.com/MobilityDB/MobilityDB/releases/tag/v1.2.2"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/mobilitydb-through-out-of-bounds-read-dos-via-wkb-deserialization"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
