In the Linux kernel, the following vulnerability has been resolved: media: iris: Add sanity check for stop streaming Add sanity check in irisvb2stopstreaming. If inst->state is already IRISINSTERROR, we should skip the streamoff operation because it would still send packets to the firmware. In iriskillsession, inst->state is set to IRISINSTERROR and sessionclose is executed, which will kfree(insthfigen2->packet). If stopstreaming is called afterward, it will cause a crash.
