CVE-2018-3639: Infoleak
Published Apr 13, 2018
·Updated
An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization).
It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire).
As a result, an unprivileged attacker could use this flaw to read privileged memory by conducting targeted cache side-channel attacks.
Other sources
EFI. An information disclosure issue was addressed with a microcode update. This ensures that older data read from recently-written-to addresses cannot be read via a speculative side-channel.
Microcode. An information disclosure issue was addressed with a microcode update. This ensures that older data read from recently-written-to addresses cannot be read via a speculative side-channel.
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 Store Bypass (SSB), Variant 4.
