This provides the QEMU part of the mitigations for the speculative store buffer bypass vulnerabilities on the x86 platform[1], and is the companion of the kernel patches merged in: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3b78ce4a34b761c7fe13520de822984019ff1a8f [1] https://bugs.chromium.org/p/project-zero/issues/detail?id=1528 https://access.redhat.com/security/vulnerabilities/ssbd The following changes since commit 9802316ed6c19fd45b4c498523df02ca370d0586: Merge remote-tracking branch 'remotes/mjt/tags/trivial-patches-fetch' into staging (2018-05-21 10:50:32 +0100) are available in the Git repository at: git://github.com/ehabkost/qemu.git tags/x86-next-pull-request for you to fetch changes up to 403503b162ffc33fb64cfefdf7b880acf41772cd: i386: define the AMD 'virt-ssbd' CPUID feature bit (CVE-2018-3639) (2018-05-21 18:59:08 -0300) ---------------------------------------------------------------- Speculative store buffer bypass mitigation (CVE-2018-3639) ---------------------------------------------------------------- Daniel P.
