CVE-2026-43217 Details
Description
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.
A vulnerability in the Linux kernel's media subsystem, specifically within the Iris Gen2 driver, has been addressed. The issue arose because the function 'iris_kill_session' would set the session state to 'IRIS_INST_ERROR' and close the session, freeing a packet associated with the session. If 'stop_streaming' was called afterward, it could lead to a crash. The vulnerability has been fixed by adding a NULL check for the packet before sending a STOP command to the firmware.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched version are available on the Linux kernel official website.
