CVE-2025-20073 Details
Description
Improper buffer restrictions in the UEFI DXE module for some Intel(R) Reference Platforms within UEFI may allow an information disclosure. System software adversary with a privileged user combined with a high complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
A vulnerability exists in the UEFI DXE module for certain Intel Reference Platforms, where improper buffer restrictions may lead to information disclosure. This vulnerability allows a system software adversary with privileged user access to expose data. The attack is complex but can potentially be executed locally, without special internal knowledge or user interaction. While the vulnerability itself may have a low impact on confidentiality, it could lead to greater confidentiality issues within the system.
Users are advised to update to the latest UEFI firmware version provided by their system manufacturer that addresses this vulnerability.
