[76689.101056] kernel BUG at mm/usercopy.c:99!

You cut the interesting part: what's one line above this?

Sorry, it actually said cut here, but I guess you want to see the line above. I just reproduced, and paste the full output: [ 33.243667] usercopy: Kernel memory exposure attempt detected from SLUB object 'dma-kmalloc-128' (offset 0, size 64)!
