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

> A memory leak in the smartpqi SCSI driver allows attackers to exhaust system memory, potentially causing a denial of service.

- **Severity:** Medium 5.5 (`CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H`)
- **Exploited in the wild:** Not known
- **Login needed:** Any signed-in user
- **Attackable:** Local or same network only
- **Victim action needed:** Not needed
- **Fix available:** Yes
- **Published:** 27 May 2026

## 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 (Missing Release of Memory after Effective Lifetime)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2026-45872 and fix it if it is affected.

What it is: 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.
Exploitation: There is no known exploitation of CVE-2026-45872 in the wild and no public exploit code.

Affected product: Linux kernel. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
