Summary
In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Fix data race on CQP request done KCSAN detects a data race on cqp_request->request_done memory location which is accessed locklessly in irdma_handle_cqp_op while being updated in irdma_cqp_ce_handler. Annotate lockless intent with READ_ONCE/WRITE_ONCE to avoid any compiler optimizations like load fusing and/or KCSAN warning.

A remote peer can therefore drive both CQP submission and completion traffic that races on the shared flag byte.\nAC:L - The attacker controls both sides of the race by driving an arbitrary rate of concurrent CQP operations (SYN/connection churn remotely, or concurrent verbs locally), which also exhausts the static request pool and forces the `kzalloc`/`dynamic` path. Non-atomic byte-wide RMW on a byte shared by three flags collides reliably at high operation rates.\nPR:N - The remote CM path that issues CQP requests runs during TCP SYN/MPA handling, before any MPA or application-level authentication. Even on the local path, `/dev/infiniband/uverbs*` is world-accessible (mode 0666) under standard rdma-core udev rules, so no privileges are needed.\nUI:N - The race is triggered purely by attacker-generated connection or verbs traffic against an already-configured RDMA device; no action by any local user or administrator is required.\nS:U - The corruption and its consequences are entirely within the kernel\u0027s own security authority \u2014 the irdma driver\u0027s request objects and the resources it manages. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - A stale `request_done` makes `irdma_handle_cqp_op()` report success while the hardware op is still in flight, so the request object is recycled while still referenced by `cqp-\u003escratch_array`, and CQ/QP/MR/DMA memory is freed while the device still owns it. The resulting use-after-free on `kzalloc`\u0027d requests gives an attacker control over freed-object contents and hence a read primitive.\nI:H - The same use-after-free leads to `cqp_request-\u003ecallback_fcn(cqp_request)` being invoked on a concurrently reused object and to refcount underflow/double free; a lost update on the adjacent `dynamic` bit additionally causes `kfree()` of a pointer inside the `kcalloc`\u0027d `cqp_requests` array (invalid free / slab corruption). Both are exploitable for kernel memory writes and control-flow hijack.\nA:H - A lost `request_done` drives the waiter to the CQP timeout, which calls `ice_rdma_request_reset(pf, IIDC_PFR)` \u2014 a full PF reset of the NIC \u2014 and latches `rf-\u003ereset`, failing all further CQP ops. A lost `waiting` bit skips `irdma_hw_modify_qp_callback()`, leaving `wait_event(iwqp-\u003emod_qp_waitq, \u2026)` (no timeout, uninterruptible) hung permanently, plus the UAF paths cause outright panics."
