Detailsinfo

A vulnerability classified as critical has been found in Intel Processors (the affected version unknown). This affects an unknown part of the component UEFI Firmware. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Improper buffer restrictions in the UEFI firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access.

The advisory is shared at intel.com. This vulnerability is uniquely identified as CVE-2024-31155 since 05/29/2024. The exploitability is told to be easy. An attack has to be approached locally. The exploitation needs additional levels of successful authentication. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 05/01/2026).

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at CERT Bund (WID-SEC-2025-0323). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
