Detailsinfo

A vulnerability classified as problematic was found in Intel Reference Platform (version unknown). Affected by this vulnerability is an unknown function of the component UEFI DXE Module. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at intel.com. This vulnerability is known as CVE-2025-20073 since 10/10/2024. The exploitation appears to be difficult. An attack has to be approached locally.
