New BIOS updates are available for Intel products, enhancing the hardening of certain UEFI variables against potential modification. Intel highly recommends that users install the updates to mitigate this exposure.
Intel has become aware that certain firmware implementations may not correctly protect and validate information contained in certain UEFI variables. Exploitation of such vulnerabilities could potentially lead to bypass of security features and/or denial of service for the platform.
To mitigate these issues, Intel is releasing firmware updates for our impacted products. Intel highly recommends that users install the updates to mitigate this exposure.
Intel would like to thank the following organizations for reporting this issue and working with us: Corey Kallenberg, Xeno Kovah, John Butterworth, and Sam Cornwell of the MITRE Corporation and Advanced Threat Research and Security Center of Excellence from Intel.
