Background
The Kernel is a fundamental component of the Linux operating system that manages system resources and provides an interface for software to interact with the hardware. It is responsible for tasks such as process management, memory management, and device drivers. The pm8001_chip_fw_flash_update_req() function in the SCSI subsystem of the Kernel is vulnerable to a memory leak. This function is used for updating firmware on PM8001 SAS/SATA controllers. A memory leak occurs when memory is allocated but not properly deallocated, leading to a gradual depletion of available memory over time.
