In the Linux kernel, the following vulnerability has been resolved: RDMA/erdma: complete object teardown when the destroy command fails erdma_destroy_qp(), erdma_destroy_cq(), erdma_dereg_mr(), and erdma_destroy_ah() returned early when erdma_post_cmd_wait() failed, leaking the queue buffers, MTTs, doorbells and the STAG, QPN, CQN and AHN identifiers. A command timeout clears ERDMA_CMDQ_STATE_OK_BIT and permanently disables the command queue, so no retry can succeed; the RDMA core keeps the object after a failed destructor and forced uverbs cleanup then nulls the pointers, making the resources unreachable. Warn on failure but release every software-owned resource and return success, since during terminal destruction the hardware command result is only diagnostic.
