Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
Add exception protection processing for vd in axi_chan_handle_err function
Since there is no protection for vd, a kernel panic will be triggered here in exceptional cases.
You can refer to the processing of axi_chan_block_xfer_complete function
The triggered kernel panic is as follows:
