  "message": "[gpu] Fix signed integer overflow in extents computation\n\nGlyph extents from malicious fonts can have extreme values\nthat overflow when computing x_bearing + width or the\nwidth/height deltas in hb_gpu_paint_encode.  Widen to int64_t\nbefore the arithmetic.\n\nFixes: https://oss-fuzz.com/testcase-detail/crash-8a9ba2164fd1e6a6fd7a8ed566cf4d0350c1357e\n\nAssisted-by: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e\n",
