CVE-2025-39772

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)
Description: A flaw exists in the Linux kernel’s drm/hisilicon/hibmc driver related to handling hibmc loading failures. When hibmc loading fails, the driver attempts to free resources using hibmc unload before mutexes within mode.config have been initialized, leading to a potential NULL pointer access. The issue is addressed by modifying a goto statement to a return statement, as hibnc hw init() does not require resource freeing in this scenario.
Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
