{"schema":"threatline.record/2","record":{"id":"CVE-2026-98352","aliases":[],"summary":"RDMA/rtrs-clt: Fix CQ pool leak when connect is interrupted","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/rtrs-clt: Fix CQ pool leak when connect is interrupted\n\nThe client borrows shared CQ credits in the ADDR_RESOLVED handler via\nib_cq_pool_get(), before the peer is connected. create_cm() can return\n-ERESTARTSYS from wait_event_interruptible_timeout() without destroying\nthe CM ID. The init_conns() and stop-and-destroy paths then call\ndestroy_con_cq_qp() while cq is still NULL (no PUT) and only afterwards\nrdma_destroy_id().\n\nCMA serializes the handler against rdma_destroy_id() with handler_mutex,\nbut that does not order the GET against destroy_con_cq_qp(). If\nADDR_RESOLVED has already passed the DESTROYING check, it can take\ncon_mutex, GET credits, and then lose the con to kfree. Device\nunregister later hits WARN_ON(cq->cqe_used) in ib_cq_pool_cleanup().\n\nSet a per-connection flag under con_mutex before CQ/QP teardown so a\nracing ADDR_RESOLVED cannot borrow credits after teardown has begun.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
