Overview

CVE-2025-71272 is a medium-severity vulnerability. It was published on May 6, 2026 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:

most: core: fix resource leak in most_register_interface error paths

The function most_register_interface() did not correctly release resources

if it failed early (before registering the device). In these cases, it

returned an error code immediately, leaking the memory allocated for the

interface.

Fix this by initializing the device early via device_initialize() and

calling put_device() on all error paths.

The most_register_interface() is expected to call put_device() on

error which frees the resources allocated in the caller. The

put_device() either calls release_mdev() or dim2_release(),

depending on the caller.

Switch to using device_add() instead of device_register() to handle

the split initialization.

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.
