Updated

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

media: chips-media: wave5: Add timeout while stopstreaming

When stopstreaming is called, an infinite loop may occur in some cases. Add a bounded poll of the queue status: loop until the queues drain, sleeping briefly between polls, and bail out once VPUDECSTOPTIMEOUT elapses.

Frequently Asked Questions

1

Which systems are affected by this issue?

Systems running the Linux kernel with the chips-media Wave5 media driver are relevant. The problem occurs during the driver's stop_streaming operation.

2

What is the practical impact if the issue is triggered?

Stopping a stream can enter an infinite loop when queue draining does not complete. This can cause the stop_streaming operation to hang indefinitely.

3

What does the fix change?

The fix replaces the unbounded wait with polling that sleeps briefly between queue-status checks and stops waiting after VPU_DEC_STOP_TIMEOUT expires. The referenced stable kernel commits contain the resolution.
