PortSmash Side Channel Attack Siphons Data From Intel, Other CPUs

Yet another side-channel attack, this time dubbed PortSmash, has been discovered in CPUs. The attack allows attackers to manipulate a glitch in the simultaneous multithreading SMT architecture used in CPUs — and siphon processed data from chips. Several attacks have popped up over the past year...

USN-3651-1: QEMU update

Ken Johnson and Jann Horn independently discovered that microprocessors utilizing speculative execution of a memory read may allow unauthorized memory reads via sidechannel attacks. An attacker in the guest could use this to expose sensitive guest information, including kernel memory. This update...

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...
