In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix out-of-bound access of qmiinvokehandler()
Currently, there is no terminator entry for ath12kqmimsg_handlers hence facing below KASAN warning,
================================================================== BUG: KASAN: global-out-of-bounds in qmiinvokehandler+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: qmimsghandler qmidatareadywork Call trace: dumpbacktrace+0x0/0x20c showstack+0x14/0x1c dumpstack+0xe0/0x138 printaddressdescription.isra.5+0x30/0x330 _kasanreport+0x16c/0x1bc kasanreport+0xc/0x14 _asanload8+0xa8/0xb0 qmiinvokehandler+0xa4/0x148 qmihandlemessage+0x18c/0x1bc qmidatareadywork+0x4ec/0x528 processonework+0x2c0/0x440 workerthread+0x324/0x4b8 kthread+0x210/0x228 retfrom_fork+0x10/0x18
The address belongs to the variable: ath12kmacmonstatusfilter_default+0x4bd8/0xfffffffffffe2300 [ath12k] [...] ==================================================================
Add a dummy terminator entry at the end to assist the qmiinvokehandler() in traversing up to the terminator entry without accessing an out-of-boundary index.
