  "title": "RDMA/counter: Fix num_counters leak on bind_qp failure in alloc_and_bind()",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  RDMA/counter: Fix num_counters leak on bind_qp failure in alloc_and_bind()  When __rdma_counter_bind_qp() fails in alloc_and_bind(), the error path jumps to err_mode which frees the counter without decrementing port_counter-\u003Enum_counters. The only place that decrements is rdma_counter_free(), which is unreachable since the counter was never successfully bound.  This leak accumulates across repeated failures, permanently preventing the port from switching to AUTO mode (-EBUSY in __counter_set_mode()) and blocking the MANUAL\u2192NONE auto-revert in rdma_counter_free(). When the mode was NONE before the call, the MANUAL mode set by __counter_set_mode() also leaks since the revert logic is never reached.  Add an err_bind label between the num_counters increment and the existing err_mode label. It decrements num_counters and mirrors the MANUAL\u2192NONE revert from rdma_counter_free(), ensuring the port state is fully restored on bind failure.",
