CVE-2019-11135 (https://nvd.nist.gov/vuln/detail/CVE-2019-11135):
  A flaw was found in the implementation of Intel Transactional
  Synchronization Extensions (TSX) abortion where a local authenticated
  attacker with the ability to monitor execution time is able to infer TSX
  memory state by comparing abort execution times.

All patches are included in

>=sys-kernel/gentoo-sources-4.19.84
>=sys-kernel/gentoo-sources-4.14.154
>=sys-kernel/gentoo-sources-4.9.202
>=sys-kernel/gentoo-sources-4.4.202

However we will wait for next kernel version to stabilize with patches for bug 699754.
