Title
Use-after-free in WebGPU internals triggered from a compromised child process
Summary
Starting with Firefox 142, it was possible for a compromised child process to trigger a use-after-free in the GPU or browser process using WebGPU-related IPC calls. This may have been usable to escape the child process sandbox. This vulnerability was fixed in Firefox 144.0.2.
