This commit: commit 6f6343f5 Author: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Date: Thu Apr 17 17:17:33 2014 +0900 kprobes/x86: Call exception handlers directly from do_int3/do_debug appears to have inadvertently dropped a check that the int3 came from kernel mode. Trying to dereference addr when addr is user-controlled is completely bogus. Signed-off-by:
