This is the AMD assigned CVE for Retbleed (CVE-2022-29900), as AMD did not
agree on the coverage for CVE-2022-29900: As stated in the Xen advisory 407:
On AMD CPUs, Retbleed is one specific instance of a more general
microarchitectural behaviour called Branch Type Confusion. AMD have
assigned CVE-2022-23816 (Retbleed) and CVE-2022-23825 (Branch Type Confusion).
Unfortunately both CVE-2022-23816 and CVE-2022-29900 are widely used by now for
