  "summary": "RDMA/erdma: complete object teardown when the destroy command fails",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/erdma: complete object teardown when the destroy command fails\n\nerdma_destroy_qp(), erdma_destroy_cq(), erdma_dereg_mr(), and\nerdma_destroy_ah() returned early when erdma_post_cmd_wait() failed,\nleaking the queue buffers, MTTs, doorbells and the STAG, QPN, CQN and AHN\nidentifiers. A command timeout clears ERDMA_CMDQ_STATE_OK_BIT and\npermanently disables the command queue, so no retry can succeed; the RDMA\ncore keeps the object after a failed destructor and forced uverbs cleanup\nthen nulls the pointers, making the resources unreachable.\n\nWarn on failure but release every software-owned resource and return\nsuccess, since during terminal destruction the hardware command result is\nonly diagnostic.",
