From a1ecf3c4560ef8260f73ffb85b425f3a046cd419 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Mon, 20 Oct 2014 18:47:34 -0300 Subject: [PATCH] [media] af9035: make sure loading modules is const Make sure that loaded modules are const char strings so we don't load arbitrary modules in the future, nor allow for format string leaks in the module request call.
