CVE-2017-1000363 (GCVE-0-2017-1000363)

Vulnerability from cvelistv5 – Published: 2017-07-13 20:00 – Updated: 2024-08-05 22:00
VLAI
Summary
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 '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) 'lp=none' arguments to the command line.
