"scenarios": [ { "lang": "en", "value": "AV:N - The rtrs-srv RDMA block-storage target reaches the vulnerable call from its RDMA_CM connect-request handler (rtrs-srv.c:1978 → __alloc_path → map_cont_bufs → ib_map_mr_sg(..., NULL)), so a remote peer's connection packet drives the deref; hns is RoCEv2 over UDP/IP and therefore routable rather than link-local.\nAC:L - The dereference of the NULL sg_offset is the first statement executed in hns_roce_map_mr_sg() with no race, timing window, or memory-layout precondition — every invocation from a NULL-passing ULP crashes deterministically.\nPR:N - In the rtrs-srv path the code is reached before any authentication — only a magic value, protocol version and cid sanity check on attacker-controlled connect private data precede it; on the client-side ULPs (NFS/RDMA, NVMe-oF, SMB Direct) an ordinary unprivileged user's file or block I/O suffices.\nUI:N - No victim action is needed; the attacker simply issues an RDMA connect request to an already-running server, or a local user performs routine I/O over an existing mount.\nS:U - The fault occurs and is contained within the kernel of the affected host with no crossing of a virtualization, IOMMU, or other security authority boundary.\nC:N - The bug is a read of virtual address 0 that immediately faults; no kernel memory contents are returned to or observable by the attacker.\nI:N - No memory is written and no attacker-controlled data is stored — the faulting access is a read used only for an IS_ALIGNED() test, so no data can be modified.\nA:H - The NULL dereference produces a kernel oops (panic with panic_on_oops, and leaves the RDMA CM handler/session in a broken state otherwise), and it is triggerable repeatedly by any remote connect attempt or local I/O, denying service to the whole system." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
