A remote RoCE peer cannot choose queue depths, so no network-triggered path exists.\nAC:L - The attacker fully controls the single condition needed \u2014 the requested queue depth \u2014 and can deterministically request a CQ/QP whose PTE count exceeds 256K pages, since the driver\u0027s only bound is the firmware-reported `max_cq_wqes`, which was uncapped in all affected versions. No race or unpredictable state is involved in reaching the faulty loop.\nPR:L - The kernel exposes the uverbs character devices with mode 0666 (`uverbs_devnode()`), and RDMA/HPC and container deployments routinely grant unprivileged users direct verbs access \u2014 that is the entire point of user-space kernel bypass. No root or capability is required to issue a create_cq/create_qp request.\nUI:N - The attacker triggers the oversized queue allocation entirely from its own process; no action by any other user or administrator is needed. Exploitation completes within a single verbs call sequence.\nS:U - The uninitialized-pointer write and the resulting corruption occur within the kernel\u0027s own memory and security authority. Although the misprogrammed PDE also causes device DMA to unintended physical addresses, this remains within the host kernel\u0027s authority rather than crossing a VM or sandbox boundary.\nC:H - The bug reads uninitialized vmalloc slots and hands the adapter a PDE whose upper entries are uninitialized DMA memory, so the NIC dereferences arbitrary physical addresses as page-table pages, allowing kernel memory to be DMA\u0027d out; the resulting memory corruption is likewise leverageable for arbitrary read.\nI:H - Writing `src_phys_ptr[i] | PTU_PDE_VALID` through an uninitialized pointer is an arbitrary/wild kernel write of a semi-controlled 64-bit value across up to 512 consecutive slots, and the stale vmalloc page contents can be groomed by the attacker via the page allocator, yielding a control-flow-hijacking primitive.\nA:H - In the common case the stale pointer is NULL (or non-canonical), producing an immediate kernel oops/panic on a fault in the write loop; any successful trigger corrupts kernel memory or programs the NIC with garbage PBL addresses, reliably crashing the system."
