Linux Kernel up to 6.17.2 mpt3sas ioc_info denial of service

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, which was classified as critical, has been found in Linux Kernel up to 6.17.2. Affected by this issue is the function ioc_info of the component mpt3sas. The manipulation with an unknown input leads to a denial of service vulnerability. Using CWE to declare the problem leads to CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. Impacted is availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: scsi: mpt3sas: Fix crash in transport port remove by using ioc_info() During mpt3sas_transport_port_remove(), messages were logged with dev_printk() against &mpt3sas_port->port->dev. At this point the SAS transport device may already be partially unregistered or freed, leading to a crash when accessing its struct device. Using ioc_info(), which logs via the PCI device (ioc->pdev->dev), guaranteed to remain valid until driver removal.
