Linux drivers/char/lp.c Out-of-Bounds Write. Due to a missing bounds check,
and the fact that parport_ptr integer is static, a β€˜secure boot’ kernel
command line adversary (can happen due to bootloader vulns, e.g. Google
Nexus 6’s CVE-2016-10277, where due to a vulnerability the adversary has
partial control over the command line) can overflow the parport_nr array in
the following code, by appending many (>LP_NO) β€˜lp=none’ arguments to the
command line.
