Описание
Improper initialization in UEFI firmware OutOfBandXML module in some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access.
A flaw was found in the Unified Extensible Firmware Interface (UEFI) firmware OutOfBandXML module used in certain Intel processors. Due to improper initialization within the module, a local attacker with administrative privileges can exploit this weakness to access sensitive system data. This issue results in information disclosure, potentially compromising confidential firmware or memory contents.
Отчет
Moderate impact: Red Hat Enterprise Linux systems using the affected microcode_ctl component may allow a privileged local user to exploit improper initialization in the UEFI firmware OutOfBandXML module on some Intel processors, potentially causing information disclosure. The local attack requires high privileges and high attack complexity, consistent with the current CVSS 3.1 score of 5.3 (Moderate), with high confidentiality impact and no integrity or availability impact. The issue affects the recorded Red Hat Enterprise Linux 7 ELS and Red Hat Enterprise Linux 8 streams, and Red Hat Enterprise Linux 9.6, for which a fix is being pursued. Red Hat Enterprise Linux 10.0 is not affected because the vulnerable code is not present.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
