  "message": "[agy][opengl] Clear mMappedData on buffer unmap\n\nWhen a buffer is unmapped in Dawn\u0027s OpenGL backend, mMappedData was\nnot cleared. If a subsequent GL operation fails during deferred\nexecution (Toggle::GLDefer), remaining queued lambdas such as a new\nglMapBufferRange may be dropped, causing FinalizeMap to latch the\nstale mapping pointer and leading to a use-after-free.\n\nThis change clears mMappedData synchronously in Buffer::UnmapImpl.\n\nFixed: 536694378\nTest: dawn_end2end_tests --gtest_filter\u003d\"*GLBufferTests*\"\nChange-Id: I81500e3bc32aeaec6bb18013220b3957aae407dd\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/337535\nReviewed-by: Shrek Shao \u003cshrekshao@google.com\u003e\nReviewed-by: Corentin Wallez \u003ccwallez@chromium.org\u003e\nCommit-Queue: Corentin Wallez \u003ccwallez@chromium.org\u003e\n",
