Hi Pavel, Confirm the patch you posted [1] is the real fix of this bug report. I tested the patch from Yanfei Xu [2] in my local workspace, and the memory leak is still triggered. In addition, I have pushed a patch request for that patch. The result would prove that patch is not working for this bug. BTW, there occur incorrect fix commits on the syzbot dashboard sometimes. Maybe it should be cleaned in the future.
