  "title": "RDMA/efa: Fix use of completion ctx after free",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  RDMA/efa: Fix use of completion ctx after free  On admin queue completion handling, if the admin command completed with error we print data from the completion context. The issue is that we already freed the completion context in polling/interrupts handler which means we print data from context in an unknown state (it might be already used again). Change the admin submission flow so alloc/dealloc of the context will be symmetric and dealloc will be called after any potential use of the context.",
