Subject: CVE-2026-45872: scsi: smartpqi: Fix memory leak in pqi_report_phys_luns()
Date: Wed, 27 May 2026 14:18:34 +0200 [thread overview]
Message-ID: <2026052713-CVE-2026-45872-0503@gregkh> (raw)
From: Greg Kroah-Hartman <gregkh@kernel.org>
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.
The Linux kernel CVE team has assigned CVE-2026-45872 to this issue.

Mitigation
==========
The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes. Individual
changes are never tested alone, but rather are part of a larger kernel
release. Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all. If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
