Reaching or influencing it requires local access to the machine (RDMA uverbs devices, memory/resource pressure, or a locally initiated reset).\nAC:L - The double destruction fires whenever `free_mr_alloc_res()` fails partway through creating the 8 reserved QPs, since the `create_failed_qp` unwind kfree()s `free_mr->rsv_qp[i]` without NULLing the array slot, leaving dangling pointers that `hns_roce_v2_exit()` → `free_mr_exit()` destroys and frees a second time. A local attacker can influence exactly that partial-failure window by driving slab/QP/CQ/PD resource exhaustion so one of the eight allocations fails after earlier ones succeeded, and the init/reset sequence is repeatable, so the required conditions are not beyond the attacker's control.\nPR:L - No authentication beyond ordinary local access is needed to create the precondition — an unprivileged user holding the usual `/dev/infiniband/uverbs*` access in an RDMA deployment can exhaust QP/CQ/PD and memory resources to make the reserved-resource allocation fail mid-loop. The init/reset trigger itself is not gated by any capability check inside the vulnerable code path.\nUI:N - The faulty unwind executes automatically inside the driver's own error path during device initialization or NIC reset recovery. No victim has to open a file, mount anything, or take any other action.\nS:U - The corrupted objects (`struct hns_roce_qp`, its lists and the kernel slab) all belong to the kernel's own security authority. There is no crossing into a hypervisor, IOMMU, or other separate security scope.\nC:H - The second `hns_roce_v2_destroy_qp()` operates entirely on freed memory — it reads `hr_qp->ibqp.send_cq`/`recv_cq` and passes them to `to_hr_cq()`/`__hns_roce_v2_cq_clean()`, and uses `hr_qp->qpn` for `__xa_erase()`. If the reclaimed slab object is groomed by the attacker, those become fully controlled pointers, yielding an arbitrary kernel-memory read primitive.\nI:H - `hns_roce_qp_remove()` performs three `list_del()` unlinks on the freed object, each writing `prev->next = next; next->prev = prev` with pointers taken from reclaimed slab memory — a classic controlled-write primitive — and the object is then kfree()d a second time, corrupting the freelist. That combination is exploitable for control-flow hijack and privilege escalation.\nA:H - The reported failure is an immediate `list_del corruption ... LIST_POISON1` WARNING in `__list_del_entry_valid()` from `hns_roce_qp_remove()`, and the double kfree() corrupts the slab allocator. This reliably produces an oops/panic and leaves the RDMA device unusable." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/infiniband/hw/hns/hns_roce_hw_v2.c", "drivers/infiniband/hw/hns/hns_roce_main.c" ], "versions": [ { "version": "fd8489294dd2beefb70f12ec4f6132aeec61a4d0", "lessThan": "dab173bae3303f074f063750a8dead2550d8c782", "status": "affected", "versionType": "git" }, { "version": "fd8489294dd2beefb70f12ec4f6132aeec61a4d0", "lessThan": "fc8b0f5b16bab2e032b4cfcd6218d5df3b80b2ea", "status": "affected", "versionType": "git" }, { "version": "fd8489294dd2beefb70f12ec4f6132aeec61a4d0", "lessThan": "10b083dbba22be19baa848432b6f25aa68ab2db5", "status": "affected", "versionType": "git" }, { "version": "fd8489294dd2beefb70f12ec4f6132aeec61a4d0", "lessThan": "c6957b95ecc5b63c5a4bb4ecc28af326cf8f6dc8", "status": "affected", "versionType": "git" }, { "version": "2ccf1c75d39949d8ea043d04a2e92d7100ea723d", "status": "affected", "versionType": "git" }, { "version": "d2d9c5127122745da6e887f451dd248cfeffca33", "status": "affected", "versionType": "git" }, { "version": "dac2723d8bfa9cf5333f477741e6e5fa1ed34645", "status": "affected", "versionType": "git" }, { "version": "60595923371c2ebe7faf82536c47eb0c967e3425", "status": "affected", "versionType": "git" }, { "version": "6.1.113", "lessThan": "6.2", "status": "affected", "versionType": "semver" }, { "version": "6.6.54", "lessThan": "6.7", "status": "affected", "versionType": "semver" }, { "version": "6.10.13", "lessThan": "6.11", "status": "affected", "versionType": "semver" }, { "version": "6.11.2", "lessThan": "6.12", "status": "affected", "versionType": "semver" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/infiniband/hw/hns/hns_roce_hw_v2.c", "drivers/infiniband/hw/hns/hns_roce_main.c" ], "versions": [ { "version": "6.12", "status": "affected" }, { "version": "0", "lessThan": "6.12", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.42", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.15.10", "lessThanOrEqual": "6.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.16.1", "lessThanOrEqual": "6.16.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.17", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.12", "versionEndExcluding": "6.12.42" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.12", "versionEndExcluding": "6.15.10" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.12", "versionEndExcluding": "6.16.1" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.12", "versionEndExcluding": "6.17" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.1.113" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.6.54" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.10.13" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.11.2" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/dab173bae3303f074f063750a8dead2550d8c782" }, { "url": "https://git.kernel.org/stable/c/fc8b0f5b16bab2e032b4cfcd6218d5df3b80b2ea" }, { "url": "https://git.kernel.org/stable/c/10b083dbba22be19baa848432b6f25aa68ab2db5" }, { "url": "https://git.kernel.org/stable/c/c6957b95ecc5b63c5a4bb4ecc28af326cf8f6dc8" } ], "title": "RDMA/hns: Fix double destruction of rsv_qp", "x_generator": { "engine": "bippy-1.2.0" } } } }
