Linux Kernel up to 6.4.3 qedf_main.c qedf_alloc_global_queues null pointer dereference

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability classified as critical has been found in Linux Kernel up to 6.4.3. This affects the function qedf_alloc_global_queues of the file drivers/scsi/qedf/qedf_main.c. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: scsi: qedf: Fix NULL dereference in error handling Smatch reported: drivers/scsi/qedf/qedf_main.c:3056 qedf_alloc_global_queues() warn: missing unwind goto? At this point in the function, nothing has been allocated so we can return directly. In particular the "qedf->global_queues" have not been allocated so calling qedf_free_global_queues() will lead to a NULL dereference when we check if (!gl[i]) and "gl" is NULL.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2023-54289 since 12/30/2025. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 319448 (EulerOS Virtualization 2.13.1 : kernel (EulerOS-SA-2026-2132)), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 5.4.251, 5.10.188, 5.15.121, 6.1.39, 6.3.13 or 6.4.4 eliminates this vulnerability. Applying the patch 961c8370c5f7e80a267680476e1bcff34bffe71a/ac64019e4d4b08c23edb117e0b2590985e33de1d/b1de5105d29b145b727b797e2d5de071ab3a7ca1/c316bde418af4c2a9df51149ed01d1bd8ca5bebf/08c001c1e9444a3046c79a99aa93ac48073b18cc/271c9b2eb60149afbeab28cb39e52f73bde9900c/f025312b089474a54e4859f3453771314d9e3d4f is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.
