Detailsinfo

A vulnerability was found in Intel Processor (the affected version is unknown). It has been classified as problematic. This affects an unknown code. The manipulation with an unknown input leads to a improper handling of values vulnerability. CWE is classifying the issue as CWE-229. The product does not properly handle when the expected number of values for parameters, fields, or arguments is not provided in input, or if those values are undefined. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Improper handling of values in the microcode flow for some Intel(R) Processor Family may allow an escalation of privilege. Startup code and smm adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present with special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (low), integrity (low) and availability (none) impacts.

The advisory is shared at intel.com. This vulnerability is uniquely identified as CVE-2025-31648 since 04/15/2025. The exploitability is told to be difficult. An attack has to be approached locally. Additional levels of successful authentication are required for exploitation. Neither technical details nor an exploit are publicly available.
