"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nipmi: fix refcount leak in i_ipmi_request()\n\nWhen a caller provides a `supplied_recv` message to i_ipmi_request(),\nthe function increments the user's `nr_msgs` reference count. If an\nerror occurs later, the out_err cleanup path only frees the recv_msg\nif the function allocated it itself (i.e., !supplied_recv). In the\nsupplied_recv case the cleanup is skipped, leaving the reference count\nelevated. The caller ipmi_request_supply_msgs() does not release the\nsupplied_recv on error, so the reference is permanently leaked.\n\nFix this by explicitly reverting the reference count operations when a\nsupplied recv_msg with a valid user pointer is present in the error\npath: decrement nr_msgs and drop the user's kref."
