      "title": "ice: add missing xa_destroy for sched_node_ids",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nice: add missing xa_destroy for sched_node_ids\n\nCommit 16dfa49406bc (\"ice: Introduce new parameters in ice_sched_node\")\nadded a sched_node_ids xarray to the port info structure, but never called\nxa_destroy on it.\n\nSince xarrays can allocate internal memory, this can result in a memory\nleak even if every element in the xarray has been removed.\n\nThe xarray is currently embedded in the port_info structure. This appears\nto have been done because its use is within functions that take the\nport_info as a primary argument.\n\nHowever, this complicates managing the lifecycle of the field. The\nport_info structure is allocated in ice_init_hw() using devm, and it is\nnot released until the devm cleanup when the driver is unloaded.\n\nThe ice_init_hw() function is called in many places, including devlink\nreload, and possibly during DDP load after updating the Tx scheduler\nlayout.\n\nAdding a call of xa_destroy to the ice_deinit_hw() causes Sashiko to raise\nmultiple concerns due to potential ordering issues and possible ways that\nport_info could be a dangling reference.\n\nTo handle this, move the sched_node_ids out of port_info and into the hw\nstructure. All users of the array already have a pointer to hw anyways, and\nthere is only one sched_node_ids per adapter. While here, remove the overly\nverbose comment explaining the nature of the sched_node_ids xarray.\n\nAdd the missing xa_destroy to the cleanup path and to ice_deinit_hw(),\nensuring that we properly release the xarray memory.\n\nThis was caught by Sashiko during development of unrelated code.",
