CVE-2022-29900

Name of the Vulnerable Software and Affected Versions Intel and AMD microprocessors (affected versions not specified) AMD microprocessor families 15h through 18h

Description The issue is related to mis-trained branch predictions for return instructions, which may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions. This can lead to the disclosure of protected information from kernel memory or enable an attack on the host system from virtual machines. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution.

Recommendations For Intel and AMD microprocessors, at the moment, there is no information about a newer version that contains a fix for this vulnerability. For AMD microprocessor families 15h through 18h, at the moment, there is no information about a newer version that contains a fix for this vulnerability.
