Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix out-of-bound access of qmi_invoke_handler() Currently, there is no terminator entry for ath12k_qmi_msg_handlers hence facing below KASAN warning, ================================================================== BUG: KASAN: global-out-of-bounds in qmi_invoke_handler+0xa4/0x148 Read of size 8 at addr ffffffd00a6428d8 by task kworker/u8:2/1273 CPU: 0 PID: 1273 Comm: kworker/u8:2 Not tainted 5.4.213 #0 Workqueue: qmi_msg_handler qmi_data_ready_work Call trace: dump_backtrace+0x0/0x20c show_stack+0x14/0x1c dump_stack+0xe0/0x138 print_address_description.isra.5+0x30/0x330 __kasan_report+0x16c/0x1bc kasan_report+0xc/0x14 __asan_load8+0xa8/0xb0 qmi_invoke_handler+0xa4/0x148 qmi_handle_message+0x18c/0x1bc qmi_data_ready_work+0x4ec/0x528 process_one_work+0x2c0/0x440 worker_thread+0x324/0x4b8 kthread+0x210/0x228 ret_from_fork+0x10/0x18 The address belongs to the variable: ath12k_mac_mon_status_filter_default+0x4bd8/0xfffffffffffe2300 [ath12k] [...] ================================================================== Add a dummy terminator entry at the end to assist the qmi_invoke_handler() in traversing up to the terminator entry without accessing an out-of-boundary index.
