RaTasha Tillery-Smith 2022-02-02 13:54:41 UTC Doc Text Fast store forwarding prediction in one domain could be controlled by software previously executed in another domain. Such control could help a malicious program running in user mode (or guest VM) to trigger transient execution gadgets in supervisor mode (or VMM), potentially leading to sensitive data disclosure. Fast store forward prediction is not enabled when SSBD is set. An authenticated user with local access may be able to perform information disclosure via transient execution. A flaw was found in microcode. Fast store forwarding prediction in one domain could be controlled by software previously executed in another domain. Such control helps a malicious program running in user mode (or guest VM) to trigger transient execution gadgets in supervisor mode (or VMM), potentially leading to sensitive data disclosure.
