{"id":"CVE-2026-119299","state":"PUBLISHED","title":"gopacket: SCTP chunk sub-decoder out-of-bounds panics on crafted segments","description":"gopacket provides packet processing capabilities for Go. 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.","publishedAt":"2026-10-30T16:23:51.655Z","updatedAt":"2026-10-30T16:54:01.623Z","severity":{"score":5.9,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["gopacket gopacket"],"affected":[{"vendor":"gopacket","product":"gopacket","versions":[{"version":"< 1.7.2","status":"affected"}]}],"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"],"weaknesses":["CWE-125","CWE-129"],"ingestedAt":"2026-10-30T16:58:06.414Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/119xxx/CVE-2026-119299.json","commit":"fe72493474485dbf6b41c09f1b2a7ef92a166950","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-119299","state":"PUBLISHED","datePublished":"2026-10-30T16:23:51.655Z","dateUpdated":"2026-10-30T16:54:01.623Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-10-29T18:50:28.066Z"},"containers":{"cna":{"title":"gopacket: SCTP chunk sub-decoder out-of-bounds panics on crafted segments","descriptions":[{"lang":"en","value":"gopacket provides packet processing capabilities for Go.
