Vulnerability Name:

CVE-2022-21127 (CCN-228695)

Assigned:2021-11-12
Published:2022-06-14
Updated:2023-01-31
Summary:Intel Processors could allow a local authenticated attacker to obtain sensitive information, caused by incomplete cleanup in specific special register read operations in the Memory Mapped I/O (MMIO) component. By conducting a specially-crafted read operation, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
