When SMT is enabled, certain AMD processors may speculatively execute instructions using a target
from the sibling thread after an SMT mode switch potentially resulting in information disclosure.
A flaw was found in HW. When SMT is enabled, certain AMD processors may speculatively execute instructions using a target from the sibling thread after an SMT mode switch, potentially resulting in information disclosure.
Statement: The Red Hat Enterprise Linux 8 and 9 are not affected if spectre_v2 mitigation enabled (and it is enabled by default).
Mitigation: The current mitigations for spectre V4 (or spectre_v2) should mitigate this flaw, no additional steps will need to be taken.
