   An update that fixes two vulnerabilities is now available.


   This update for the Linux Kernel 4.4.120-94_17 fixes several issues.

   The following security issues were fixed:

   - CVE-2018-3646: Local attackers in virtualized guest systems could use
     speculative code patterns on hyperthreaded processors to read data
     present in the L1 Datacache used by other hyperthreads on the same CPU
     core, potentially leaking sensitive data, even from other virtual
     machines or the host system (bsc#1099306).
   - CVE-2018-10853: A flaw was found in kvm. In which certain instructions
     such as sgdt/sidt call segmented_write_std didn't propagate access
     correctly. As such, during userspace induced exception, the guest can
     incorrectly assume that the exception happened in the kernel and panic.
