The issue is related to a use-after-free vulnerability in the WebGPU interface, which can be exploited by a remote attacker to execute arbitrary code. There have been reports of attacks in the wild abusing this flaw. The vulnerability is associated with the WebGPU IPC framework, where an unexpected message could lead to a use-after-free and exploitable sandbox escape.
