Details:
It was discovered that some Intel processors did not completely perform cleanup actions on multi-core shared buffers. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21123)
It was discovered that some Intel processors did not completely perform cleanup actions on microarchitectural fill buffers. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21125)
It was discovered that some Intel processors did not properly perform cleanup during specific special register write operations. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21166)

Please note that fully mitigating processor vulnerabilities requires corresponding processor microcode/firmware updates.
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
