What to do
AI-suggested
A fix has been applied in the Linux kernel to destroy internal buffers after the firmware releases them. Users should update to the fixed kernel version once available. No additional mitigation steps are indicated.
Description
A vulnerability in the Linux kernel's iris gen1 media driver caused internal buffers to remain allocated after the firmware released them, leading to wasted memory until the session closed. This issue was fixed by ensuring the driver destroys internal buffers once the firmware release response is received.
