Prior to 1.40, OpaqueObjLoader::CreateStream in src/server/rdb_load.cc can associate one streamNACK with a consumer group's global PEL and a consumer-local PEL, then free the shared object when a duplicate consumer entry is rejected. Cleanup subsequently frees the same object again. In the default configuration, where Dragonfly ships with authentication disabled, an unauthenticated client can trigger the double-free by sending a crafted serialized stream to RESTORE, causing allocator corruption, denial of service, and potentially attacker-controlled code execution as the Dragonfly service account. The source fix has not yet been mapped to a published release.","state":0,"publishedAt":"2026-10-13T14:42:54.248+00:00","modifiedAt":"2026-10-13T15:26:00.663+00:00","affected":[{"ecosystem":"Vendor product","name":"dragonfly","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"dragonflydb\",\n                    \"product\": \"dragonfly\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.40\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","score":9.6,"severity":"CRITICAL"}],"references":["https://github.com/dragonflydb/dragonfly/security/advisories/GHSA-cg35-6jf4-crfh","https://github.com/dragonflydb/dragonfly/pull/7929","https://github.com/dragonflydb/dragonfly/commit/6c6b27a5cfd03d67eb9583ab84a0f0709e3bc77e"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-104192","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-104192","identifiers":["CVE-2026-104192"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
