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