Welcome to your comprehensive guide on CVE-2024-24853, a significant security concern that has been flagged with a HIGH severity rating and a CVSS score of 7.2. This article aims to provide our readers, especially those utilizing Intel hardware in their systems, with an expert understanding of the issue, its potential impacts, and the steps required to mitigate the risk effectively.
CVE-2024-24853 involves an incorrect behavior order in the transition between executive monitor and System Management Interrupt (SMI) transfer monitor (STM) in certain Intel Processors. This vulnerability could potentially allow a privileged user, such as someone with administrative access, to escalate their privileges through local access. The targeted manipulation of this transition can lead to compromised system integrity, allowing attackers to execute higher privilege operations than permitted under normal operations.
This vulnerability specifically affects Intel processors that support the transition between executive monitoring and SMI transfer monitoring. Intel processors are widely used in various computational devices ranging from personal computers to large servers and cloud-based computing environments, making this vulnerability particularly concerning due to its broad applicability and potential impact in multi-user and multi-tenant environments.
The System Management Mode (SMM) of Intel processors is designed to handle various system-wide control and management functions, including power management, system hardware control, and other direct management tasks that operate at the highest privilege level in computing environments. The SMI Transfer Monitor (STM) is an extension of this mode, providing additional security assurances by isolating the execution of system management code from the operating system's normal execution context.
The misuse of the vulnerability can lead to severe security consequences. By exploiting CVE-2024-24853, an attacker with local access and sufficient privileges could install programs; view, change, or delete data; or create new accounts with full user rights. It’s crucial for system administrators and security professionals to understand the seriousness of this risk as it can compromise the confidentiality, integrity, and availability of the systems.
To mitigate the risks associated with CVE-2024-24853, it is recommended that users apply firmware updates provided by Intel and system manufacturers as soon as they become available. Additionally, monitoring for unusual system behavior and privilege escalation attempts can help in early detection of attempts to exploit this vulnerability:
