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


* CVE-2017-12192: Denial-of-service when reading negative key.

Invalid memory access when reading key negative from kernel key management
facility results in a crash. An unprivileged local user can exploit this
to cause denial-of-service.
