speculatively execute instructions using a return address from a sibling
thread. A local attacker could possibly use this to expose sensitive
information. (CVE-2022-27672)

Daniel Moghimi discovered that some Intel(R) Processors did not properly
clear microarchitectural state after speculative execution of various
instructions. A local unprivileged user could use this to obtain to
sensitive information. (CVE-2022-40982)
