6266be9b8a61acc30af19182c101d562fb18af4d WebGPU async pipeline creation stalls rendering
not a security fix
confidence 0.15
signal score 21.43
Source/WebGPU/
Classified as not security-relevant.
Triage note: Reworks Device::createComputePipeline/createRenderPipeline into a callback-based async MSL compile (prepareLibrary/compileLibrary/createPipelineStateAsync, claim pipelineId up front, resolve bind-group layout before the descriptor can die); the lifetime/id comments describe invariants of the NEW async design, not a pre-existing exploitable bug in the previously-synchronous path.
This commit was flagged by the signal scorer and reviewed by AI (not a human). It is listed only so the triage is auditable; there is no root-cause analysis because this is not a vulnerability fix.
