Description

When a socket is closed for a child process, the closeClientSocket call is executed. If this is done through SessionProcessManager::processDeadChildren(), this can happen safely, behind a mutex.

However, this call can also come from a ProxyReply, which does not run this behind a mutex. This can lead to a race condition.
