{"id":"DEBIAN-CVE-2026-88358","details":"simdjson 4.6.1 contains a one-byte out-of-bounds read vulnerability in dom::parser::parse_unpadded(). A specially crafted truncated JSON document whose final structural token closes a nested array or object can cause json_iterator::walk_document() to access buf[len] after the input buffer has been exhausted. This results in a heap out-of-bounds read and may cause application termination, leading to denial of service.","modified":"2026-09-29T09:00:25.714117194Z","published":"2026-09-24T16:17:13.090Z","upstream":["CVE-2026-88358"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-88358"}],"affected":[{"package":{"name":"simdjson","ecosystem":"Debian:12","purl":"pkg:deb/debian/simdjson?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.0.1-1","3.10.1-1","3.10.1-1~exp1","3.12.0-1","3.12.0-2","3.12.2-1","3.12.3-1","3.13.0-1","3.13.0-1.1","3.2.1-1","3.2.1-1~exp1","3.2.3-1","3.6.0-1~exp1","3.6.3-1","3.6.3-1~exp1","3.6.4-1","3.9.4-1~exp1","4.2.3-1","4.2.4-1","4.3.1+really4.2.4-1","4.3.1+really4.3.1-1","4.3.1-1","4.3.1-2","4.3.1-4","4.3.1-5","4.5.0-1","4.6.0-1","4.6.11-1","4.6.3-1","4.6.4-1","4.6.5-1","4.6.6-1","4.6.7-1","4.6.8-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88358.json"}},{"package":{"name":"simdjson","ecosystem":"Debian:13","purl":"pkg:deb/debian/simdjson?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.12.3-1","3.13.0-1","3.13.0-1.1","4.2.3-1","4.2.4-1","4.3.1+really4.2.4-1","4.3.1+really4.3.1-1","4.3.1-1","4.3.1-2","4.3.1-4","4.3.1-5","4.5.0-1","4.6.0-1","4.6.11-1","4.6.3-1","4.6.4-1","4.6.5-1","4.6.6-1","4.6.7-1","4.6.8-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88358.json"}},{"package":{"name":"simdjson","ecosystem":"Debian:14","purl":"pkg:deb/debian/simdjson?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.12.3-1","3.13.0-1","3.13.0-1.1","4.2.3-1","4.2.4-1","4.3.1+really4.2.4-1","4.3.1+really4.3.1-1","4.3.1-1","4.3.1-2","4.3.1-4","4.3.1-5","4.5.0-1","4.6.0-1","4.6.11-1","4.6.3-1","4.6.4-1","4.6.5-1","4.6.6-1","4.6.7-1","4.6.8-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88358.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
