Prior to 1.7.2, the SCTP chunk chain in layers/sctp.go passes attacker-controlled declared lengths and counts to decodeSCTPInit, decodeSCTPShutdown, decodeSCTPError, decodeSCTPSack, and decodeSCTPParameter without checking that each chunk contains the fixed fields, parameter TLVs, gap acknowledgements, or duplicate TSNs those sub-decoders read. A crafted SCTP segment can therefore cause out-of-bounds or inverted slice panics; the panic can terminate applications that use gopacket.DecodeOptions.SkipDecodeRecovery, direct registered decoders, or DecodingLayerParser with IgnorePanic enabled, while the default recovery-enabled APIs convert it to a per-packet decode error. This is the SCTP sub-decoder residual named but not remediated by CVE-2026-65819, whose version 1.7.1 changes bounded the generic dispatcher but left these per-type reads and loops unchecked. The impact is availability only, with no data disclosure, modification, or allocation amplification. This issue is fixed in version 1.7.2.","score":5.9,"severity":"medium","published":"2026-10-30T16:23:51.655Z","modified":"2026-10-30T16:54:01.623Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"gopacket","name":"gopacket","platforms":[],"versions":[{"version":"< 1.7.2","status":"affected"}],"cpes":[],"source":"GitHub_M","url":"https://www.cve.org/CVERecord?id=CVE-2026-119299"}],"remediation":[],"references":["https://github.com/gopacket/gopacket/security/advisories/GHSA-358w-w75h-x6rx","https://github.com/gopacket/gopacket/commit/508044327cc2c065b3db753c010a027e7d1ca621","https://github.com/gopacket/gopacket/releases/tag/v1.7.2"],"sources":[{"name":"CVE","id":"CVE-2026-119299","modified":"2026-10-30T16:54:01.623Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-119299"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","score":5.9}],"sourceAffected":[],"observedAt":"2026-10-30T17:26:59.509Z","kev":{"status":"not-listed","checkedAt":"2026-10-31T10:20:31.211Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-10-30T17:40:35.209Z","attemptedAt":"2026-10-30T17:40:35.209Z"},{"source":"GHSA","status":"no-result","checkedAt":"2026-10-30T17:40:35.190Z","attemptedAt":"2026-10-30T17:40:35.190Z"},{"source":"EUVD","status":"no-result","checkedAt":"2026-10-30T17:40:34.143Z","attemptedAt":"2026-10-30T17:40:34.143Z"},{"source":"EPSS","status":"no-result","checkedAt":"2026-10-30T17:40:34.044Z","attemptedAt":"2026-10-30T17:40:34.044Z"}],"evidence":[{"source":"NVD","id":"CVE-2026-119299","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-119299","modified":"2026-10-30T17:17:18.230","score":5.9,"vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","checkedAt":"2026-10-30T17:40:35.209Z"}],"aiSummary":null}
