CVE-2022-23825

23
FAUCET Score

CVE-2022-23825 is a medium-severity vulnerability affecting AMD processors, as well as products from Debian, Fedora, and VMware. It involves aliases in the branch predictor that could lead to incorrect branch type predictions, potentially resulting in information disclosure. The attack requires local access with low complexity, and while it has a high confidentiality impact, it does not affect integrity or availability. This vulnerability is not actively exploited, lacks public exploit code, and is not on the KEV catalog, though it has garnered significant community discussion and media coverage, including reports on the "Inception" side-channel attack.
