This update for ucode-intel fixes the following issues :

Updated Intel CPU Microcode to 20200602 (prerelease) (bsc#1172466)

This update contains security mitigations for :

CVE-2020-0543: Fixed a side channel attack against special registers which could have resulted in leaking of read values to cores other than the one which called it. This attack is known as Special Register Buffer Data Sampling (SRBDS) or 'CrossTalk' (bsc#1154824).

CVE-2020-0548,CVE-2020-0549: Additional ucode updates were supplied to mitigate the Vector Register and L1D Eviction Sampling aka 'CacheOutAttack' attacks. (bsc#1156353)
