  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ncxgb4/ch_ktls: disable softirqs around tid_list erases\n\nchcr_ktls_cpl_act_open_rpl() inserts into tid_list from the receive path\nusing xa_insert_bh().  The array is shared by the adapter's connections\nand initialized with XA_FLAGS_LOCK_BH.  However, chcr_ktls_dev_del() and\nthe chcr_ktls_dev_add() error path use xa_erase(), which takes the XArray\nlock without disabling softirqs.\n\nWhen cleanup runs with softirqs enabled, a receive softirq for another\nconnection on the same CPU can interrupt the erase and spin on the lock\nheld by the interrupted task.  Use xa_erase_bh() at both sites to match\nthe insertion path.",
