CVE-2026-45872 scsi: smartpqi: Fix memory leak in pqi_report_phys_luns()

What is CVE-2026-45872?

CVE-2026-45872 is a medium-severity denial of service vulnerability in Linux kernel, published on 27 May 2026. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

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.

Weakness: CWE-401
