  "details": "In the Linux kernel, the following vulnerability has been resolved:  nvmet-tcp: fix page fragment cache leak in error path  In nvmet_tcp_alloc_queue(), when a connection is closed during the allocation process (e.g., nvmet_tcp_set_queue_sock() returns -ENOTCONN), the error handling jumps to out_destroy_sq and then to out_ida_remove without draining the page fragment cache.  Although nvmet_tcp_free_cmd() is called in some error paths to release individual page fragments, the underlying page cache reference held by queue-\u003epf_cache is never released. The first allocation using pf_cache is the call to nvmet_tcp_alloc_cmd() for queue-\u003econnect, which happens after ida_alloc() returns successfully. This results in a page leak each time a connection fails during allocation, which could lead to memory exhaustion over time if connections are repeatedly opened and closed.  Fix this by calling page_frag_cache_drain() before freeing the queue structure in the out_ida_remove label.",
