What is CVE-2025-39772?

A vulnerability in the Hisilicon Hibmc driver within the Linux kernel is triggered when hibmc fails to load. During the unloading process, the driver attempts to free resources despite the mutexes in mode.config not being initialized. This flaw leads to the potential access of a NULL pointer, which could cause unpredictable behavior in the system. A code modification has been made to change the flow of execution, ensuring that the system does not attempt to free resources unnecessarily, thereby improving stability and reliability.
