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 problematic, was found in Linux Kernel up to 6.6.147/6.12.100/6.18.41/7.1.4. This affects the function dw_edma_pcie_probe of the component dmaengine. 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: dmaengine: dw-edma-pcie: Reject devices without driver data dw_edma_pcie_probe() treats the PCI device ID driver_data as the template for the controller layout and copies it unconditionally. A device bound dynamically via sysfs can match the driver without that data, which leads to a NULL pointer dereference. Reject such matches before enabling the device.

It is possible to read the advisory at git.kernel.org. This vulnerability is uniquely identified as CVE-2026-72147 since 08/09/2026. The exploitability is told to be easy. Attacking locally is a requirement. Additional levels of successful authentication are required for exploitation. It demands that the victim is doing some kind of user interaction. Technical details of the vulnerability are known, but there is no available exploit.

Upgrading to version 6.6.148, 6.12.101, 6.18.42, 7.1.5 or 7.2-rc1 eliminates this vulnerability. Applying the patch 2733b5dcb5a4ba4446f7bac954b97e4501dcaa64/a1042599fa8f9e313be176eb1ea1ae199f983419/043acb00e4edd4b9ffb9dd0e357482dcd9086486/044f7b3252d4fb2143d4999eec2800c08f1001ed/11d7cfe0c119691b2dafbb699bbca90258c678aa is able to eliminate this problem.
