Description
In the Linux kernel, the following vulnerability has been resolved: drm/hisilicon/hibmc: fix the hibmc loaded failed bug When hibmc loaded failed, the driver use hibmc_unload to free the resource, but the mutexes in mode.config are not init, which will access an NULL pointer. Just change goto statement to return, because hibnc_hw_init() doesn't need to free anything.

Executive Summary

This vulnerability occurs in the Linux kernel's drm/hisilicon/hibmc driver. When the hibmc driver fails to load, it attempts to free resources using hibmc_unload, but the mutexes in mode.config are not initialized, leading to a NULL pointer access. The fix involved changing a goto statement to a return to avoid freeing uninitialized resources.

Impact Analysis

The vulnerability can cause the system to access a NULL pointer during driver unload, which may lead to system instability or crashes when the hibmc driver fails to load properly.
