CVE-2026-45872 Details
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.
A memory leak vulnerability has been identified in the Linux kernel's SmartPQI SCSI driver. The issue arises in the 'pqi_report_phys_luns' function, which fails to properly release the 'rpl_list' buffer when it encounters an unsupported data format or when the allocation for the 'rpl_16byte_wwid_list' fails. These premature returns skip the necessary cleanup, resulting in memory leaks. The vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The specific commit that resolves this issue is '41b37312bd9722af77ec7817ccf22d7a4880c289', which is included in the official Linux kernel repository.
