Daniel Moghimi discovered Gather Data Sampling (GDS), a hardware vulnerability for Intel CPUs which allows unprivileged speculative access to data which was previously stored in vector registers.
This mitigation requires updated CPU microcode provided in the intel-microcode package and released as ELA-935-1.
