2025.1 IPU - Intel® Processor Advisory, INTEL-TA-01153, May 2025

A processor event or prediction may allow incorrect operations (or correct operations with incorrect data) to execute transiently, potentially exposing data over a covert channel. Indirect branch predictions may not be fully constrained by enhanced IBRS properties and the Indirect Branch Predictor Barrier. This update applies to the X11, X12, and X13 families of products powered by Intel Xeon® and other Intel processors.

More Information:

Skilled users with user authentication via local operating system access can potentially impact confidentiality(high) through information disclosure by means of exposure of sensitive information in shared microarchitectural structures during transient execution in some Intel® Processors.

Security Advisories that affect BIOS:

  • INTEL-SA-01153 – 2025.1 IPU - Intel® Processor Advisory
    • Summary: A potential security vulnerability in some Intel® Processors may allow information disclosure. Intel is releasing microcode updates and prescriptive guidance to mitigate this potential vulnerability.
