What it actually does
Use-after-free triggered when rxe_qp_from_init fails, leaving QP structure with uninitialized pointers that rxe_qp_do_cleanup later dereferences during kref_put and refcount operations.
Why it matters to the business
Systems using the Linux soft RDMA driver (rxe) may experience kernel crashes or memory corruption during RDMA device initialization or QP creation failures, leading to service disruption on affected hosts.
How an attack unfolds
An attacker with local access triggers repeated failures in rxe_qp_from_init during RDMA MAD port setup or device registration, causing the error path to pass garbage pointers into cleanup routines that perform reference count decrements on invalid memory.
How to fix it
Update the Linux kernel to a version containing the fix that clears all QP fields on creation failure before any cleanup runs; rebuild and reboot affected systems.
How to confirm the fix worked
Confirm the kernel source contains the clearing of QP fields in the rxe_qp_from_init error path; run syzkaller or targeted RDMA QP creation failure tests to verify absence of refcount underflow warnings.
Typical attack path
- Obtain local execution on a Linux host with the rxe soft RDMA driver loaded
- Trigger RDMA device registration or MAD initialization paths that call rxe_create_qp
- Force rxe_qp_from_init to fail so that QP fields contain uninitialized values
- Allow rxe_elem_release and rxe_qp_do_cleanup to execute kref_put on the corrupted structure
- Observe refcount underflow warning and subsequent use-after-free
How to detect it
Search kernel logs for refcount_warn_saturate messages referencing rxe_qp_do_cleanup or rxe_create_qp; inspect crash dumps showing kref_put on RDMA QP structures during ib_register_device or mad initialization.
What your security team should do
- Prioritize kernel updates on systems exposing RDMA interfaces or running rxe
- Monitor for refcount underflow warnings in kernel logs during device bring-up
- Disable the rxe module if RDMA software emulation is not required
The record
In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Clear all QP fields if creation failed rxe_qp_do_cleanup() relies on valid pointer values in QP for the properly created ones, but in case rxe_qp_from_init() failed it was filled with garbage and caused tot the following error. refcount_t: underflow; use-after-free.
