Multiple CPUs - Information Leak Using Speculative Execution

== INTRODUCTION == This is a bug report about a CPU security issue that affects processors by Intel, AMD and to some extent ARM. I have written a PoC for this issue that, when executed in userspace on an Intel Xeon CPU E5-1650 v3 machine with a modern Linux kernel, can leak around 2000 bytes per...

Huawei Mate cell phone information leakage vulnerability

FreeBSD : FreeBSD -- Kernel data leak via ptrace(PT_LWPINFO) (34a3f9b5-dab3-11e7-b5af-a4badb2f4699)

Not all information in the struct ptracelwpinfo is relevant for the state of any thread, and the kernel does not fill the irrelevant bytes or short strings. Since the structure filled by the kernel is allocated on the kernel stack and copied to userspace, a leak of information of the kernel stack...
