Description

Security researcher Ronald Crane reported a race condition in GetStaticInstance in WebRTC which results in a use-after-free. This could result in a potentially exploitable crash. This issue was found through code inspection and does not have clear mechanism to be exploited through web content but is vulnerable if a mechanism can be found to trigger it.
