On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

* CVE-2019-11135: Side-channel information leak in Intel TSX.

A side-channel information leak on some generations of Intel processors
could allow the leaking of internal microarchitectural buffers during
asynchronous aborts in a TSX transaction.  For CPUs that are vulnerable
to Microarchitectural Data Sampling, existing mitigations cover
CVE-2019-11135, for newer CPUs with hardware fixes for MDS, TSX is
transparently disabled.  On these newer CPUs, TSX functionality can be
restored by writing 0 to /sys/kernel/debug/x86/tsx_force_abort.
