Description
A memory leak vulnerability was identified and fixed in the Linux kernel's scsi smartpqi driver within the function pqi_report_phys_luns(). The issue occurs when the function encounters unsupported data formats or allocation failures, causing early returns that skip cleanup and lead to memory leaks. The fix consolidates error handling to ensure proper resource release on failure.
