Overview

CVE-2025-39709 is a medium-severity vulnerability. It was published on September 5, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

media: venus: protect against spurious interrupts during probe

Make sure the interrupt handler is initialized before the interrupt is

registered.

If the IRQ is registered before hfi_create(), it's possible that an

interrupt fires before the handler setup is complete, leading to a NULL

dereference.

This error condition has been observed during system boot on Rb3Gen2.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
