Noticing webrtc rolls change in the CL range,

@emircan -- Could you please look into the issue, kindly re-assign if this is not related to your changes.
Thank You.

hlundin@, can you PTAL to see if it is related to the CL below?
https://chromium.googlesource.com/external/webrtc/+/79dfdadbc861a56596a42ba9f40c8bcbf30e4d75

I would not think that the indicated CL is to blame as such. Rather, I think that CL fixed another problem, which enabled the fuzzer to probe deeper and find this new problem. Nevertheless, I'll take this bug.

Ivo, please, take a look at this.
