[28] CONFIG_PROFILING=n - Profiling support can potentially allow user space to gather dangerous debugging information about the kernel. CONFIG_PROC_PAGE_MONITOR=n - /proc pag...
eliminate any risk of ASLR bypass due to the vsyscall fixed address mapping. Attempts to use the vsyscalls will be reported to dmesg, so that either old or malicious userspace programs can be identified. endchoice config CMDLINE_BOOL bool "Built-in kernel command line" help...

Using a generic kernel version for production applications is a bad idea because it makes KASLR bypass easier.A second mitigation concerns the kernel code. Since the entire exploit runs in the context of the Linux kernel, we need to think of changes to the Linux kernel itself. We...

kernel-hardening-checker是一款针对Linux内核的安全加固工具,广大研究人员可以使用该工具检查并实现 Linux 内核安全强化选项。 Linux 内核有很多安全强化选项。其中很多选项在主流发行版中都没有启用。我们必须自己启用这些选项,才能让我们的系统更安全。但很多人并不喜欢手动检查这些选项,kernel-hardening-checker便应运而生...
't put any intentional effort to bypass Control-Flow Integrity. However, for each of the exploitation steps, we consciously picked the most flexible and the most robust primitives. Turns-out, that our selection somehow avoided any of the primitives that could potentially be blocked by Control-...
