Name of the Vulnerable Software and Affected Versions AMD processors (affected versions not specified)

Description 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. This issue is related to errors occurring after a core exits the C0 sleep state. Exploitation of this issue may allow an attacker to disclose protected information, including access to the return address predictor cache.
