    At least one susbsystem rolls its own method of adding env vars to the
    uevent buffer, and it's so broken it triggers the WARN_ON() in
    lib/vsprintf.c::vsnprintf() by passing a negative length to that function.
    Start at drivers/input/input.c::input_dev_uevent() and watch the fun.

    I reported this to linux-kernel, the input maintainer and the author
