Intel CPU (SRBDS / CrossTalk): Special Register Buffer Data Sampling
CVSS 5.5CVE-2020-0543Kernel, userspace & hypervisorcurated
Impact
Special Register Buffer Data Sampling - leaks RDRAND/RDSEED output across cores, i.e. across tenants on the same socket
Who can reach it
Any tenant process in a container; tenant VM guest
What to do
Microcode + reboot; the mitigation serialises RDRAND/RDSEED with a large measured cost on RNG-heavy workloads
