Linux Kernel up to 7.1.4 ims-pcu usb_fill_int_urb input validation

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, has been found in Linux Kernel up to 7.1.4. Affected by this issue is the function usb_fill_int_urb of the component ims-pcu. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: Input: ims-pcu - validate control endpoint type The driver currently assumes that the first endpoint of the control interface is an interrupt IN endpoint without verifying it. A malicious device could provide a different endpoint type, which would then be passed to usb_fill_int_urb(), potentially leading to kernel warnings or undefined behavior. Verify that the control endpoint is an interrupt IN endpoint.

The advisory is shared for download at git.kernel.org. This vulnerability is handled as CVE-2026-72078 since 08/09/2026. The exploitation is known to be easy. The attack needs to be approached locally. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 08/15/2026).
