Shulou(Shulou.com)11/24 Report--

CTOnews.com March 4, Intel reported on June 14, 2022 that there was a MMIO stale data vulnerability in Intel's 6th-generation Core processors and Xeon E processors. Microsoft today released a new set of security patches to fix the above security vulnerabilities in Win10 and Win11 systems.

An attacker who successfully exploits these vulnerabilities may read privileged data across trust boundaries. In a shared resource environment, such as in some cloud service configurations, these vulnerabilities may allow one virtual machine to incorrectly access information in another virtual machine. On stand-alone systems in non-browsing scenarios, attackers must access the system or be able to run specially designed applications on the target system before they can exploit these vulnerabilities.

These vulnerabilities include:

CVE-2022-21123-shared buffer data read (SBDR)

CVE-2022-21125-shared buffer data sampling (SBDS)

CVE-2022-21127-Special register buffer data sampling update (SRBDS update)

CVE-2022-21166-device register partial write (DRPW)
