      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/core: Fix potential use after free in ib_free_cq()\n\nWhen accessing a CQ via the netlink path the only synchronization\nmechanism for the said CQ is rdma_restrack_get().\nCurrently, rdma_restrack_del() is invoked at the end of\nib_free_cq(), which is too late, since by that point\nvendor-specific resources associated with the CQ might already be\nfreed. This can leave a short window where the CQ remains accessible\nthrough restrack, leading to a potential use-after-free.\n\nFix this by moving the rdma_restrack_del() call to be before the freeing\nof the vendor-specific resources ensuring that the CQ is removed from\nrestrack before its internal resources are released.\nThis guarantees that no new users hold references to a CQ that is in\nthe process of destruction.",
