"value": "AV:L - The dangling `rxe->ndev` is dereferenced from local paths — RDMA netlink link add/del, netdev up/down/unregister events, and uverbs QUERY_PORT/ATTACH_MCAST on /dev/infiniband/uverbsN. Incoming RoCEv2 packets use `skb->dev` rather than the cached pointer, so there is no remote trigger.\nAC:L - The attacker drives both halves deterministically: bring the netdev down to queue `ib_cache_event_task`, then delete the netdev so `free_netdevs()` drops the last reference before `flush_workqueue(ib_wq)` runs the pending work. syzbot reproduced it, and the sequence can be looped until it lands.\nPR:L - On a system with Soft-RoCE already configured, the UAF dereference sites (`rxe_query_port`, `rxe_mcast_add`/`rxe_mcast_del`) are reachable by any local unprivileged user through the world-accessible uverbs character device and sysfs port attributes. This matches the scoring of the same class of RDMA lifetime UAFs (CVE-2025-22085, CVE-2025-38022, CVE-2025-38024).\nUI:N - The entire sequence is performed by the attacker via netlink and verbs calls; no victim action or cooperation is needed.\nS:U - The freed `struct net_device` and the corrupting code both live in the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a slab use-after-free on `struct net_device`; the attacker can spray the freed slab and have `dev_get_flags()`/`netif_running()`/`netdev_name()` read back reclaimed content, and the leaked port state and device-name data flow back to userspace via query_port and dev_info.\nI:H - `dev_mc_add()`/`dev_mc_del()` on the freed netdev perform list manipulation into reclaimed slab memory and then indirect-call `dev->netdev_ops->ndo_set_rx_mode` through a freed function-pointer table, giving a write and control-flow-hijack primitive.\nA:H - The confirmed KASAN slab-use-after-free read in `dev_get_flags()` panics the kernel with `panic_on_warn`/KASAN and readily oopses otherwise, and the multicast paths corrupt freed heap state leading to further crashes."
