DESCRIPTION

* CVE-2020-0543: Side-channel information leak using SRBDS.

A side-channel information leak on some generations of Intel processors
could allow the leaking of internal microarchitectural buffers used by
instructions like RDRAND, RDSEED and SGX EGETKEY.

Updated microcode is required for this vulnerability to be mitigated.

The status of the mitigation can be found using the following command:
$ cat /sys/devices/system/cpu/vulnerabilities/srbds


* Various Spectre-V1 information leaks in KVM.

Various array accesses in KVM lack protection against Spectre variant
1 type attacks. An attacker could exploit this bug to read privileged
kernel memory.
