Breaking: New UEFI Vulnerability Discovered in Intel CPUs

Security Flaw in Phoenix SecureCore UEFI Firmware

Recently, cybersecurity researchers uncovered a significant security flaw in the Phoenix SecureCore UEFI firmware, impacting a wide range of Intel Core desktop and mobile processors. Known as CVE-2024-0762 with a CVSS score of 7.5, this vulnerability dubbed as “UEFIcanhazbufferoverflow” is an issue that arises from a buffer overflow caused by an insecure variable in the Trusted Platform Module.

Understanding Buffer Overflow Vulnerabilities

Buffer overflow vulnerabilities are a common and serious issue in software security. They occur when a program writes more data to a block of memory, or buffer, than it can hold. This excess data can corrupt adjacent memory locations, leading to erratic behavior or crashing of the program. In the context of UEFI firmware, a buffer overflow flaw can potentially be exploited by attackers to execute malicious code or gain unauthorized access to a system.

The Impact on Intel Core Processors

Given that the affected UEFI firmware is used in various Intel Core processors, the impact of this vulnerability is widespread. Intel processors are widely used in both desktop and mobile devices, making this security flaw a significant concern for a large number of users. It underscores the importance of promptly addressing such vulnerabilities to prevent potential security breaches and unauthorized access to sensitive information.
