Description OSIDB Bzimport 2025-09-11 17:02:56 UTC 
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.
