That substitution is\nwhat an RDS/TCP socket sending to a local address gets, and after it\nthe path init loop still runs for the TCP transport's RDS_MPATH_WORKERS\npaths and allocates an ordered workqueue for each, while\nrds_loop_conn_alloc() only ever provides transport data for path 0.\n\nrds_conn_destroy() sizes its teardown from c_trans, by then the\nloopback transport, so it visits path 0 only - and\nrds_conn_path_destroy() would skip the other paths anyway, since it\nreturns before destroy_workqueue() for a path without transport data.\nkfree(c_path) then drops the last pointers to seven workqueues.  That\nrepeats for every such connection, on every netns teardown or module\nunload, and every distinct local destination address is a separate\nconnection.\n\nRecompute npaths once the transport is final, so that creation and\ndestruction agree on the set of paths.  The c_path array stays sized\nfor the caller's transport; the unused entries are freed with it.","state":0,"publishedAt":"2026-10-18T15:18:27.162+00:00","modifiedAt":"2026-10-19T09:21:44.401+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"net/rds/connection.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"4716af3897e95997d08183d351cece2dec9ee0c0\",\n                            \"lessThan\": \"670f303169d2d36f315c40f6d3d18b5ee8498fea\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"4716af3897e95997d08183d351cece2dec9ee0c0\",\n                            \"lessThan\": \"ba3d1f480c7a3fba963e7867ad6cc557c197acbc\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"net/rds/connection.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"7.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"7.0\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.9\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/670f303169d2d36f315c40f6d3d18b5ee8498fea","https://git.kernel.org/stable/c/ba3d1f480c7a3fba963e7867ad6cc557c197acbc"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-98560","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-98560","identifiers":["CVE-2026-98560"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
