Vulnerability from github – Published: 2026-01-13 18:31 – Updated: 2026-01-13 18:31

Details

In the Linux kernel, the following vulnerability has been resolved:

media: iris: Add sanity check for stop streaming

Add sanity check in iris_vb2_stop_streaming. If inst->state is already IRIS_INST_ERROR, we should skip the stream_off operation because it would still send packets to the firmware.

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.
