Technical details
The vulnerability involves undefined behavior that can be triggered through the misuse of JsArrayBuffer::external using safe code. The issue occurs when external buffers are manipulated in a way that can lead to use-after-free scenarios, particularly in multi-threaded contexts where the buffer might be dropped while still being referenced (GitHub Issue).
Impact
