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

media: qcom: iris: use disable_irq() during power-off

The IRQ is registered as a threaded IRQ.

Using disable_irq_nosync() in iris_vpu_power_off() does not wait
for an already queued threaded IRQ handler to complete before
returning.

As a result, a threaded IRQ handler may still run after the VPU has
been powered down and access hardware registers after power-off.

Replace disable_irq_nosync() with disable_irq() so the power-off path
waits for any in-flight threaded IRQ handler to complete before
returning.
