Does renderer use /dev/shm shared memory

Does renderer use /dev/shm shared memory?

If yes, since chromium zygote drops the file system access, I would assume that renderer will not have access to /dev/shm

When the renderer process needs to create shm, it brokers that through the browser process. See https://source.chromium.org/chromium/chromium/src/+/main:content/app/content_main.cc;l=384;drc=317154f193cfe466e41fb1ad2c4a2717a3197442, which is responsible for installing the hooks to make this work in sandboxed processes.
