Linux Kernel up to 6.4.4 scsi snprintf array index

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, was found in Linux Kernel up to 6.4.4. This affects the function snprintf of the component scsi. The manipulation with an unknown input leads to a array index vulnerability. CWE is classifying the issue as CWE-129. The product uses untrusted input when calculating or using an array index, but the product does not validate or incorrectly validates the index to ensure the index references a valid position within the array. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Array index may go out of bound Klocwork reports array 'vha->host_str' of size 16 may use index value(s) 16..19. Use snprintf() instead of sprintf().

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2023-54179 since 12/30/2025. Technical details are known, but no exploit is available. The price for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 06/07/2026).
