What is CVE-2018-3620?

This vulnerability arises from how systems with microprocessors utilizing speculative execution and address translations can inadvertently allow an attacker with local user access to disclose sensitive information. By exploiting a terminal page fault alongside side-channel analysis tactics, unauthorized users may be able to gain access to confidential data stored in the L1 data cache. This poses a significant risk for systems utilizing affected Intel processors, necessitating immediate attention and mitigation actions to safeguard sensitive information.
