[PATCH v8 1/4] syscalls: Verify address limit before returning to user-mode

2017-04-27 Thread Thomas Garnier
Ensure that a syscall does not return to user-mode with a kernel address limit. If that happens, a process can corrupt kernel-mode memory and elevate privileges [1]. The CONFIG_ADDR_LIMIT_CHECK option disables the generic check so each architecture can create optimized versions. [1]
