In the Linux kernel, the following vulnerability has been resolved:
media: iris: gen2: Add sanity check for session stop
In iris_kill_session, inst->state is set to IRIS_INST_ERROR and session_close is executed, which will kfree(inst_hfi_gen2->packet). If stop_streaming is called afterward, it will cause a crash.
Add a NULL check for inst_hfi_gen2->packet before sendling STOP packet to firmware to fix that.
