Vulnerability from github – Published: 2026-05-06 12:30 – Updated: 2026-05-11 21:31

Details

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.

Severity ?

5.5 (Medium)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
