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.\n\n## Affected\n\n- `Linux >= 4716af3897e95997d08183d351cece2dec9ee0c0 < 670f303169d2d36f315c40f6d3d18b5ee8498fea`\n- `Linux >= 4716af3897e95997d08183d351cece2dec9ee0c0 < ba3d1f480c7a3fba963e7867ad6cc557c197acbc`\n- `Linux 7.0`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
