[GitHub] [incubator-nuttx] patacongo opened a new issue #1329: System calls require address checks

patacongo opened a new issue #1329:
URL: https://github.com/apache/incubator-nuttx/issues/1329


   As a security measure, system calls such as read() or any other system call that modifies memory, must verify that the user-provided addresses lie in user-space.  Otherwise, this opens a back door that may be exploited to take control of the OS or to crash the OS.
   
   This applies only to PROTECTED and KERNEL build modes.
