**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 5.1.13 **Description** The issue is related to an uncontrolled resource consumption in the Linux kernel's `drivers/scsi/libsas/sas expander.c` component. It is caused by a memory leak that occurs when SAS expander discovery fails, leading to a denial of service. **Recommendations** For Linux kernel versions prior to 5.1.13, update to version 5.1.13 or later to resolve the issue.
