CVE-2026-45872: scsi: smartpqi: Fix memory leak in pqi_report_phys_luns()
Noroxi assessment
Priority: Monitor (action score 22/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Linux Linux 41b37312bd9722af77ec7817ccf22d7a4880c289, 454570434114e4862767f506a442a0f110b639b2, d52e13122d3771f753dd73ae6512fa01f58015cb.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to Linux Linux 41b37312bd9722af77ec7817ccf22d7a4880c289, 454570434114e4862767f506a442a0f110b639b2, d52e13122d3771f753dd73ae6512fa01f58015cb or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
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.
