Prior to 10.0.9, RTPChannel.OnRTPPacketReceived and the STUNAttribute.ParseMessageAttributes, STUNXORAddressAttribute, and STUNAddressAttribute parsing path index untrusted bytes without sufficient length checks, while UdpReceiver.EndReceiveFrom closes the channel when those operations raise a non-socket exception. A remote party can send a single short RTP packet or malformed zero-to-seven-byte STUN address attribute to the shared RTP/ICE socket, including during ICE connectivity checks before DTLS or STUN MESSAGE-INTEGRITY verification, and terminate the active RTP or WebRTC media session. The attacker must reach or learn the advertised ephemeral RTP/ICE port, but no authentication or user interaction is required, and the impact is limited to availability. This issue is fixed in version 10.0.9.","state":0,"publishedAt":"2026-09-14T19:58:30.394+00:00","modifiedAt":"2026-09-15T14:43:28.069+00:00","affected":[{"ecosystem":"Vendor product","name":"sipsorcery","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"sipsorcery-org\",\n                    \"product\": \"sipsorcery\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 10.0.9\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/sipsorcery-org/sipsorcery/security/advisories/GHSA-28gm-jrmw-xx93","https://github.com/sipsorcery-org/sipsorcery/pull/1677","https://github.com/sipsorcery-org/sipsorcery/commit/bdb76cbc0c7216e3126f743fb78e8525af56cea2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-54632","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-54632","identifiers":["CVE-2026-54632"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
