{"id":"UBUNTU-CVE-2026-119299","details":"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.","modified":"2026-11-04T03:30:26.959191411Z","published":"2026-11-03T00:00:00Z","upstream":["CVE-2026-119299"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-119299"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-119299"},{"type":"REPORT","url":"https://github.com/gopacket/gopacket/security/advisories/GHSA-358w-w75h-x6rx"},{"type":"REPORT","url":"https://github.com/gopacket/gopacket/commit/508044327cc2c065b3db753c010a027e7d1ca621"},{"type":"REPORT","url":"https://github.com/gopacket/gopacket/releases/tag/v1.7.2"}],"affected":[{"package":{"name":"golang-github-gopacket-gopacket","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/golang-github-gopacket-gopacket?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.0-1","1.2.0-1","1.2.0-2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.2.0-2","binary_name":"golang-github-gopacket-gopacket-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119299.json"}},{"package":{"name":"golang-github-gopacket-gopacket","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/golang-github-gopacket-gopacket?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.0-2"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-gopacket-gopacket-dev","binary_version":"1.3.0-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119299.json"}},{"package":{"name":"golang-github-gopacket-gopacket","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/golang-github-gopacket-gopacket?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.0-2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.3.0-2","binary_name":"golang-github-gopacket-gopacket-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119299.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
