Bug#978753: usercopy: Kernel memory exposure attempt
Hello, It probably was src:linux because it was in the original bug report I submitted a couple of minutes earlier. I included everything reportbug wanted me to include in the report. I don't know if I can run the reportbug anymore, since I am now upgrading from 10 to 11.

I'm asking because 'src:linux-image-4.19.0-13-amd64' doesn't exist (it should be either 'linux-image-4.19.0-13-amd64' or 'src:linux'). Also the report seems to be missing some (but not all?) information reportbug normally collects about the kernel. Do you get a different output if you run reportbug linux-image-4.19.0-13-amd64 ? Kind regards, Andrei
