CVE-2018-3639

Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Stor...

UBUNTU-CVE-2018-3640

Systems with microprocessors utilizing speculative execution and that perform speculative reads of system registers may allow unauthorized disclosure of system parameters to an attacker with local user access via a side-channel analysis, aka Rogue System Register Read RSRE, Variant 3a...

Speculative Store Bypass

ISSUE DESCRIPTION Contemporary high performance processors may use a technique commonly known as Memory Disambiguation, whereby speculative execution may proceed past unresolved stores. This opens a speculative sidechannel in which loads from an address which have had a recent store can observe a...
