description: |
This microcode update provides the Intel 20180807 microcode release
that adds the processor microcode side of fixes and mitigations for
the now publically known security issue affected Intel processors
called L1 Terminal Fault (L1TF) for most Intel processors since
Intel Core gen2:
Systems with microprocessors utilizing speculative execution and Intel
Software Guard Extensions (Intel SGX) may allow unauthorized disclosure
of information residing in the L1 data cache from an enclave to an
attacker with local user access via side-channel analysis (CVE-2018-3615).
Systems with microprocessors utilizing speculative execution and address
translations may allow unauthorized disclosure of information residing in
the L1 data cache to an attacker with local user access via a terminal
page fault and side-channel analysis (CVE-2018-3620).
Systems with microprocessors utilizing speculative execution and address
translations may allow unauthorized disclosure of information residing in
the L1 data cache to an attacker with local user access with guest OS
privilege via a terminal page fault and side-channel analysis
(CVE-2018-3646).
The impact of the L1TF security issues:
* Malicious applications may be able to infer the values of data in the
operating system memory, or data from other applications.
* A malicious guest virtual machine (VM) may be able to infer the values
of data in the VMM’s memory, or values of data in the memory of other
guest VMs.
* Malicious software running outside of SMM may be able to infer values
of data in SMM memory.
* Malicious software running outside of an Intel® SGX enclave or within an
enclave may be able to infer data from within another Intel SGX enclave.
NOTE! You also need to install one of the 4.14.64 based kernel updates
to get the current operating system side set of fixes and mitigations
for L1TF. That means either kernel (mga#23458), kernel-tmb (mga#23459)
or kernel-linus (mga#23460).
