**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 5.4.14 **Description** The issue is related to the ` mptctl ioctl` function in `drivers/message/fusion/mptctl.c` and involves synchronization errors when using a shared resource. This can lead to a race condition, specifically a "double fetch" vulnerability, allowing an attacker to impact the confidentiality, integrity, and availability of protected information. The vendor notes that the security impact is limited because the affected operations are privileged and the root user already has significant destructive power. **Recommendations** For Linux kernel versions prior to 5.4.14, update to version 5.4.14 or later to resolve the issue. As a temporary workaround, consider restricting access to the ` mptctl ioctl` function to minimize the risk of exploitation.
