Doc Text:
A flaw was found in the Linux kernel's `scsi: smartpqi` driver. The `pqi_report_phys_luns()` function fails to properly release allocated memory buffers under certain error conditions, such as encountering an unsupported data format or failed memory allocation. This oversight leads to a memory leak, which could potentially impact system stability or performance over time.

Description OSIDB Bzimport 2026-05-27 15:14:01 UTC 
In the Linux kernel, the following vulnerability has been resolved:

scsi: smartpqi: Fix memory leak in pqi_report_phys_luns()

pqi_report_phys_luns() fails to release the rpl_list buffer when
encountering an unsupported data format or when the allocation for
rpl_16byte_wwid_list fails. These early returns bypass the cleanup logic,
leading to memory leaks.

Consolidate the error handling by adding an out_free_rpl_list label and use
goto statements to ensure rpl_list is consistently freed on failure.

Compile tested only. Issue found using a prototype static analysis tool and
code review.
